Shown by e-readers in the library; leave empty to keep what the document says.

PDF/A-2b embeds all fonts so the file looks the same in many years; required by many courts and public offices.

Scales every sheet so it fits on a single page instead of being split across several.

Sheets

CSV and TSV hold one table: with “Every sheet” each sheet becomes its own file, together in a ZIP.

Separator

Excel in many European languages expects a semicolon; most other programs a comma.

Convert on our server?

If you continue, the file is uploaded over an encrypted connection and converted on our server. You can keep using the site meanwhile. The original is deleted as soon as it is converted; the result is kept for 7 days so you can download it, and you can delete it at any time. Files are never shared or used for anything else.

Images and PDFs are converted in your browser. Videos are converted on our server only after you accept the upload. If a file is too large for your browser or in a format it can’t handle, we ask before converting it on our server. The original is deleted right after conversion; the result is kept for 7 days for you to download, unless you delete it sooner. Privacy details

About this tool

One place for all your conversions. Every file is identified by its content, not its name, and gets only the conversions that make sense for it: images to JPG, PNG, WebP, AVIF, GIF, BMP, TIFF, ICO or PDF, and PDF documents to images, page by page.

Mix freely – iPhone HEIC photos, screenshots, scans and PDFs in the same batch. Each file has its own target and options, several files convert at the same time, and you can combine images into one PDF.

Files are converted in your browser at full quality unless you change the options. Only a file your browser cannot handle is sent to our server, and only after you agree.

Frequently asked questions

Which files can I convert?

Images (JPG, PNG, WebP, HEIC, SVG, AVIF, GIF, BMP, ICO, TIFF) and PDF documents. Each file is recognised from its content and offered the outputs that work for it.

Can I convert different files to different formats at once?

Yes. Every file has its own output; “Convert all to” sets the same output for every file that supports it.

Can I turn several images into one PDF?

Yes. Choose PDF for the images and tick “Combine into one PDF”; page size, margins and images per page are under Options.

Is the quality reduced?

No. Conversions are made at full quality until you change the quality or size in Options.

Are my files uploaded?

Normally not: conversion happens in your browser. A file your browser cannot handle is only sent to our server after you agree, and you can delete the result at any time.
