- Convert images to PNG for lossless quality when sharing screenshots or logos.
Frequently asked questions
- Are my images uploaded to a server?
- No. All conversion happens entirely in your browser using the Canvas API. Your images never leave your device — there's no upload step.
- How much smaller will my WebP files be?
- WebP is typically 25–35% smaller than equivalent JPEG or PNG files at the same visual quality. AVIF can be even smaller — up to 50% compared to WebP — but browser support for AVIF creation via Canvas is more limited.
- Why does PNG conversion ignore the quality slider?
- PNG is a lossless format — it doesn't use lossy quality compression. Every PNG is full quality by definition. The quality slider only applies to lossy formats: WebP, JPEG, and AVIF.
- What image formats can I upload?
- You can upload PNG, JPG/JPEG, WebP, AVIF, GIF, BMP, and most other browser-supported image formats. Animated GIFs will be converted as a static first frame.
- What quality setting should I use for WebP?
- 85 is a good default — visually identical to the original for most images with a significant file size reduction. For photos where quality is critical, use 90–95. For thumbnails or previews, 70–80 works well.
