FAQ

Common questions

Is my image uploaded?

No. Conversion happens locally in your browser.

Which output format should I choose?

Use WebP for smaller web files, JPG for compatibility and PNG when you need transparency.

JPG, PNG and WebP compared

JPG is suited to photographs and offers broad compatibility, but it does not support transparency. PNG preserves transparent pixels and sharp edges, often at a larger size. WebP supports transparency and usually compresses photographic content efficiently.

Conversion changes the file encoding, not the source dimensions. It cannot restore quality previously lost through compression or turn a small image into a detailed one.

Accepted input and exact limits

The converter reads JPG, PNG, WebP, GIF, BMP and AVIF files up to 20 MB and 40 million decoded pixels. It exports JPG, PNG or WebP using browser canvas encoding.

Animated sources are exported as a still frame. When JPG is selected, transparent pixels are placed on white. Use PNG or WebP when transparency matters.

Quality and file size

The quality control applies to JPG and WebP. Begin near 85, inspect text and edges, and reduce gradually if a smaller file is more important. PNG export is lossless and therefore ignores this control.

A different extension does not guarantee a smaller file. Flat graphics may favor PNG, while photographs usually favor WebP or JPG. Compare the displayed byte sizes before downloading.

Why a conversion may fail

Some browsers cannot decode every AVIF profile or unusual image variant. A file can also exceed the pixel limit after decoding even when its compressed size looks small.

Try a current version of Chrome, Edge, Firefox or Safari. If transparency looks white, the chosen output is JPG; switch to PNG or WebP and process the original again.
