Lower resolutions reduce file size. The video will not be enlarged.

Bitrate

Higher means better sound and a larger file. “Auto” keeps the bitrate of the original (at least 128 kbit/s); from lossless files it uses the format’s high-quality setting.

Pages to convert

Several pages arrive as a ZIP with one image per page.

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.

Your images are processed in your browser and are not uploaded. 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

Use this converter when you have files in several formats, or don't want to look for the right converter page. It recognises every file by its content, not its name, and only offers formats that make sense for it.

It reads JPG, PNG, WebP, HEIC, AVIF, GIF, BMP, TIFF, ICO, SVG images and PDF documents. Images can be saved as JPG, PNG, WebP, AVIF, GIF, BMP, TIFF, ICO or PDF (one PDF per image, or several combined into one); PDF pages become images at the resolution you choose.

Which format should you choose?

  • JPG: best for photos when you need maximum compatibility. No transparency.
  • PNG: lossless and supports transparency. Best for screenshots, logos and graphics, and for images you will edit again.
  • WebP and AVIF: much smaller files than JPG or PNG at similar quality, with transparency. Supported by all modern browsers, but not by every program.
  • PDF: for documents, forms and printing.

Several files are converted at the same time, so small files are ready while large ones are still being processed. Animated GIF and WebP files are converted using their first frame. Files are converted in your browser.

Frequently asked questions

Which formats are supported?

Input: JPG, PNG, WebP, HEIC, AVIF, GIF, BMP, TIFF, ICO, SVG and PDF. Output: JPG, PNG, WebP, AVIF, GIF, BMP, TIFF, ICO and PDF. PDF pages can be saved in any of these image formats except ICO.

Why is WebP output not available in my browser?

Creating WebP files depends on the browser. Most browsers can, but some versions of Safari cannot. When that happens the tool explains it and, if available, offers to create the WebP on our server with your permission.

What happens to animated GIFs?

The first frame is converted to a still image. JPG, PNG and WebP still images can't hold animation.

Is there a limit on the number of files?

You can add up to 50 files at a time. Several are converted at the same time, as far as your device’s memory allows, so small files don’t have to wait for large ones.
