How to use convert jpg, png and webp

  1. Choose your image files file. Drop the file onto the upload area or pick it from your device. The file is read straight into your browser and is not uploaded anywhere.
  2. Set the options. Adjust the settings shown for convert jpg, png and webp. The defaults suit most files, so you can usually leave them alone.
  3. Check and save the result. Run the tool and download the modified image files file. Compare it against your original before you rely on it — conversions do not always carry every detail across.

Privacy

By default this page does the work itself and your file never leaves the device. If JavaScript is unavailable, the form posts to the server instead, where the file is processed in a temporary folder and deleted as soon as the result is written. The result link works once and expires.

Questions

What happens to my file?

By default nothing leaves your device — the tool runs in your browser. If JavaScript is unavailable the same page falls back to a server form, where the file is processed in a temporary folder and deleted the moment the result is written.

Will this change anything else in my file?

No. Convert JPG, PNG and WebP changes only what the options above describe; the rest of the document is carried through untouched. Resizing or re-saving a lossy image reprocesses the pixels, so quality is lost each time. Editing repeatedly from the same original avoids compounding it.

Will this reduce the quality of my image?

Only where the format requires it. Lossless formats such as PNG survive processing unchanged, while JPEG is re-encoded and loses a little detail each time it is saved. Where quality matters, work from your original rather than from a file that has already been through several rounds.

Is there a file size limit?

In your browser the limit is your device memory rather than a fixed number. If the page falls back to the server — with JavaScript switched off — uploads are capped at 32 MB.

Working with image files

About image files

Raster images store a grid of pixels. The format decides how that grid is compressed and what extra information travels with it.

Resizing or re-saving a lossy image reprocesses the pixels, so quality is lost each time. Editing repeatedly from the same original avoids compounding it.

Troubleshooting

  • Nothing happens after choosing a file. Check the file really is IMG — a renamed extension fails here the same way it fails in other readers.
  • The upload is refused. Files over 32 MB are rejected. Split the document first, or use one of the browser-side tools, which are limited only by your device memory.
  • The result looks different from the original. Some conversions cannot carry every feature across formats. The page says what was dropped when that happens.
