Guide
Key points
- Use JPG or WebP for photos, PNG for logos and screenshots.
- Saving as JPG fills transparent areas with white.
- Images are processed in your browser and never uploaded.
JPG, PNG or WebP?
- JPG: lossy, small files, no transparency. Best for photos and maximum compatibility.
- PNG: lossless, larger files, supports transparency. Best for logos, icons and screenshots with text.
- WebP: usually smaller than JPG at the same quality and supports transparency. Best for websites.
Converting a photo to PNG keeps its quality but often makes the file larger.
Transparency
PNG and WebP keep transparent areas. JPG has no transparency, so transparent areas are filled with white.
How much quality do you lose?
- Around 80% quality is visually indistinguishable for most photos while cutting file size a lot.
- Below about 60%, edges start to smear and color banding appears.
- The quality setting applies to JPG and WebP only; PNG is lossless.
- Reducing the width and height often saves more space than lowering quality.
Supported files and limits

FAQ
Can I convert several images at once?
Not yet — one image at a time.
Will quality drop?
JPG and WebP are lossy, so lower quality settings lose detail. Around 80% is visually indistinguishable for most photos. PNG is lossless.
Is location data kept?
No. Metadata such as GPS location (EXIF) is removed during conversion.
