Sets the format for every file; change individual files in the list.

Image quality

Lower values give smaller files but lower quality. 80 is a good balance for photos; 90+ for graphics with text.

Max file size

Optional. Set a limit such as 500 KB for upload forms; quality is reduced automatically to meet it.

Transparency

Transparent areas are filled with this colour, so the result has a solid background.

Best quality

The same engines the professionals use — SVGO, resvg, MozJPEG, libwebp, libavif — compiled to run in your browser.

Private & secure

Files are processed on your device and never uploaded. Close the tab and nothing remains anywhere.

For photographs, WebP at quality 80 matches a JPG at quality 85–90 visually while weighing about a third less. That difference compounds across a gallery or product catalogue, which is why every major site converted years ago. This page opens the Image Converter pre-set to WebP output.

JPGs are already lossy, so converting compounds compression slightly; from a high-quality JPG (85+) the effect is invisible. If you still have the camera original or a PNG export, convert from that instead for the cleanest result.

This is a pre-set view of the Image Converter. Every option in the toolbar can still be changed.

Frequently asked questions

Which quality should I use for photos?

80 is the standard choice. Drop to 70–75 for large background images where size matters most; go to 85–90 if the photo contains text or fine texture you will zoom into.

Does converting JPG to WebP lose quality?

A little, because both formats are lossy — but at quality 80 the loss is below what the eye can detect at normal viewing size. Converting from an uncompressed source (PNG, TIFF, camera original) avoids the double compression entirely.

What about EXIF data and orientation?

Orientation is applied so the WebP appears the right way up. Other metadata (camera model, GPS location) is not carried over — a privacy benefit for photos you publish.

Your files never leave your device

Most online converters upload your file to a server. InfyTool ships the actual encoders to your browser as WebAssembly instead, so processing happens inside your tab — faster for batches, and nothing to delete afterwards.

No upload, ever. Turn off Wi-Fi after the page loads and every tool keeps working.
No limits. No file-size cap, no queue, no watermark, no account.
Runs on your CPU. Batches use several cores in parallel; nothing is throttled.
