Convert anything ↔ PDF ● 100% in your browser

Convert to and from PDF without uploading anything

Most free converters ask you to hand your document to a stranger's server, wait in a queue, then accept a watermark or a page cap. This one does the whole job on your own machine. Pick a conversion, drop the file in, and the finished document is saved straight to your downloads — no account, no upload, no watermark, no size games.

Everything you can convert

Into a PDF

• Images → PDF — JPG, PNG, WebP, GIF and BMP, one page per image, fitted to the picture or laid onto A4 / US Letter with your choice of margin.
• HEIC → PDF — the format an iPhone shoots in, decoded in the browser and paged up.
• Word → PDF — .docx typeset into a clean PDF with headings, bold and italic, lists, tables and embedded pictures preserved as real text.
• Excel → PDF — .xlsx, .xls or .csv laid out as tidy ruled tables, one section per sheet.
• Text / Markdown → PDF — upload a .txt or .md file, or just paste into the box. Markdown headings, lists, quotes, code blocks and rules are all rendered.
• HTML file → PDF — a saved web page converted to its text content, with scripts and styling stripped.
• SVG → PDF — vector artwork rasterised at 2× and paged.
• PowerPoint → PDF — .pptx slides redrawn from the slide XML (beta).

Out of a PDF

• PDF → Images — every page as PNG or JPG at 96, 150 or 300 DPI, delivered as a ZIP (or a single file for a one-page document).
• PDF → Word — a real .docx, with paragraph breaks and heading sizes inferred from the layout rather than one giant block of text.
• PDF → Excel — column gaps are detected and turned into real spreadsheet cells, one sheet per page.
• PDF → PowerPoint — each page becomes a full-bleed slide in a .pptx.
• PDF → Text / Markdown — all the text, optionally with headings marked up as Markdown.
• PDF → Grayscale — an ink-saving black-and-white copy for printing.
• Extract images — every embedded photo and graphic pulled out as PNG in a ZIP.

Signatures

• Image → signature PNG — a photo or scan of your handwritten signature with the paper removed, saved as a transparent PNG you can drop into any document. The paper level is measured across the picture rather than as one brightness cutoff, so an unevenly lit phone photo works as well as a flatbed scan; dust and speckle are cleaned up by size relative to your pen; and you can keep the pen's own colour or force it to black or blue. Every ordinary picture format is accepted, including the HEIC an iPhone shoots photos and screenshots in.

Print tools

• Booklet maker — reorders and pairs pages so a printed stack folds into a booklet.
• N-up printing — 2, 4 or 8 pages to a sheet.
• Poster split — one page enlarged across 4 or 9 sheets to tape together.
• Resize pages — rescale a whole document between A4, US Letter and A5.

How a conversion works

1. Pick the conversion from the grid above. Each card is one job — there is no mode to set first and no wizard to sit through.
2. Add your file. Drop it on the target area or click to browse. Several of the tools take more than one file at a time: images and HEIC photos become one PDF in the order you added them, and you can remove any of them from the list before converting.
3. Set the options, if that conversion has any. They are deliberately few — page size and margin going into a PDF, format and resolution coming out of one — because those are the choices that actually change the result.
4. Press Convert. A progress bar runs while the work happens on your machine; nothing is queued behind other people's jobs and nothing is throttled.
5. The file saves itself to your downloads. Multi-file results (page images, extracted pictures, a split document) arrive as a ZIP, except where there is only one file to give you.

Choosing settings that matter

Resolution, when you turn a PDF into images

The DPI choice is the difference between a small file and a usable one:

• 96 DPI — screen resolution. Fine for a thumbnail, a forum post or a quick preview, and the smallest files by a wide margin.
• 150 DPI — the sensible default. Text stays crisp on screen at full size and prints acceptably.
• 300 DPI — print resolution. Use it when the image is going to be printed, placed in a document at full size, or read closely. Expect roughly ten times the file size of 96 DPI.

PNG keeps text edges sharp and is the right pick for pages that are mostly type or line art. JPG makes much smaller files and suits pages that are mostly photographs. If you are unsure, PNG at 150 DPI is a safe pair.

Page size and margin, when you turn images into a PDF

Fit image makes each page exactly the size of the picture on it — no white bands, no cropping — which is what you want for a scanned receipt, a screenshot or a photo album. Choose A4 or US Letter instead when the result is going to be printed or filed alongside other documents, so every sheet matches. The margin setting then decides how much white space frames each picture: None for edge-to-edge, Small for a tidy border, Large when there needs to be room for a staple, a hole punch or a comment in the edge.

What converts faithfully — and what doesn't

Every converter has a boundary. Being told where it is beforehand is worth more than a promise that everything works:

• Word → PDF carries headings, bold and italic, lists, tables and embedded images across as real, selectable text. What it does not attempt is a pixel-exact replica of Word's own pagination: complex multi-column layouts, text boxes, footnotes, headers and footers, and tracked changes are simplified or dropped. For a contract or an essay it is excellent; for a designed brochure, print to PDF from Word itself.
• Excel → PDF lays each sheet out as a ruled table of the values in the cells. Formulas are shown as their results, which is almost always what you want in a PDF; cell colours, conditional formatting, merged-cell trickery and charts are not carried over.
• PowerPoint → PDF is marked beta for a reason. It reads the slide XML and redraws text and pictures at their recorded positions, so a straightforward text-and-image deck comes out well. Gradients, SmartArt, charts, animations, transitions and unusual fonts are approximated or skipped.
• PDF → Word / Excel reads the text objects that are actually in the PDF and infers structure from where they sit on the page — paragraph breaks and heading sizes for Word, column boundaries for Excel. It is genuinely editable output rather than one giant block, but it is a reconstruction, not the original document. It also needs a text-based PDF: run OCR in the PDF Editor first if yours is a scan, or every page will come back empty.
• PDF → images / PowerPoint / grayscale are pixel-faithful by nature — what you see is what you get, because the page is rendered exactly as a PDF reader would draw it.
• Booklet, N-up and poster embed the original pages as vector content rather than re-rendering them, so text stays sharp at any size and the file does not balloon.

The print tools, explained

Booklet maker

A booklet is not simply "two pages per sheet". Fold a stack of paper in half and the page that ends up next to page 1 is the last page, not page 2 — so the pages have to be reordered into printer spreads before they are paired up. That reordering, called imposition, is what this does. It pads the document to a multiple of four (a folded sheet always carries four pages), works out the pairing, and lays them two-to-a-sheet in landscape.

Print the result double-sided, flipping on the short edge. That flip setting is the part people get wrong: flip on the long edge and every other side comes out upside down. Then fold the whole stack in half together and staple through the spine. The pages will read in order.

N-up printing

Two, four or eight pages on a single sheet. Four-up is the sweet spot for proofreading a long document or handing out slides — still readable, a quarter of the paper. Eight-up is for seeing the shape of something rather than reading it. Two-up is close to a booklet layout without the folding.

Poster split

The opposite job: one page blown up across four sheets (2 × 2) or nine (3 × 3), for a classroom display, a sign or a seating plan. Print them, trim the white edge off two sides of each sheet, and tape them together working from the middle outwards. A 3 × 3 split of an A4 page makes something close to A0.

Resize pages

Rescales a whole document between A4, US Letter and A5, scaling the content to match rather than cropping it. This is the fix for the two everyday annoyances: an American document that prints with the bottom cut off on European paper, and the reverse.

Which tool for which job

• "I need to email these photos as one document." Images → PDF (or HEIC → PDF from an iPhone), page size Fit image.
• "The form I was sent is a Word file and they want a PDF back." Word → PDF. If you need to fill it in first, do that in Word, or convert and then use the PDF Editor.
• "I need this PDF's table in a spreadsheet." PDF → Excel. If the PDF is a scan, OCR it first.
• "I want to put a PDF page into a slide deck or a document." PDF → Images at 300 DPI, then insert the PNG.
• "This file is too big to email." PDF → Grayscale often halves it if the content is black text on white; otherwise use Compress in the PDF Editor.
• "I'm printing a 40-page handbook." Booklet maker, then fold and staple.
• "I want the pictures out of this brochure." Extract images.
• "I have a folder of notes in Markdown." Text / Markdown → PDF — upload the file or paste straight into the box.

Limits worth knowing about

• Very large files depend on your device. Everything happens in your browser's memory, so a 500-page PDF converted to 300 DPI images will ask a lot of a phone and very little of a laptop. There is no page cap imposed by us — the limit is your own hardware.
• The first run of a tool needs a connection. The HEIC decoder, the spreadsheet reader, the Word reader and the Markdown parser are fetched on demand the first time you pick a conversion that needs them, then cached. Your files are never part of that request.
• Password-protected PDFs need to be unlocked first. Open it in the PDF Editor with its password and save an unprotected copy.
• Links, bookmarks and form fields do not survive a round trip. Converting a PDF to Word and back produces a flat document. If you need to keep interactivity, edit the PDF directly instead of converting it.
• Colour is RGB. That is right for screens and for ordinary office printers. A commercial print shop asking for CMYK with crop marks needs a prepress tool, not this.

Why it runs in your browser

Conversion used to mean uploading. A server somewhere received your document, converted it, held it for a while and — if the terms were honest — deleted it later. That is a lot of trust to extend for a job that takes four seconds, and it is why so many of those sites cap pages, queue you, or stamp a watermark on the way out: their costs scale with your files.

Browsers can now do this work themselves. PDF rendering, PDF writing, ZIP packing, spreadsheet parsing and Word parsing all exist as open-source libraries that run as ordinary code on your machine, and this page is a front end for them. The practical consequences are all in your favour: no queue, no page cap, no watermark, no account, no retention policy to read — and a contract, a payslip or a medical letter never leaves the computer you are sitting at.

Privacy

Your files are never uploaded. They are read, converted and written back entirely on your own computer, and nothing about their contents is recorded. The only network traffic a conversion causes is fetching the open-source engine it needs — the HEIC decoder, the spreadsheet reader, the Word reader or the Markdown parser — the first time you use that particular tool. Your documents are not part of that request.

Nothing is stored between visits either: close the tab and the file, the converted result and the settings are gone from memory. Our full Privacy Policy covers what the site as a whole does and does not collect.

Need to edit rather than convert?

The PDF Editor annotates, edits existing text, signs, redacts, fills forms, OCRs scans and reorganises pages — also entirely in your browser. The Notepad is the place for plain text and code, and the Workbook Builder lays out printable worksheets from scratch. None of them upload anything.
