Example workflows
| Large photo | Limit max width to 1600px and export WebP for web use. |
|---|---|
| Screenshot | Try JPG or WebP with 0.8 quality, then check text readability. |
| Transparent PNG | Use PNG if transparency must be preserved, but expect less compression. |
Image format comparison
| JPG | Good for photos and broad compatibility, but it does not preserve transparency. |
|---|---|
| PNG | Good for transparency and sharp UI graphics, but photo files can remain large. |
| WebP | Often produces smaller web images in modern browsers, especially for photos and previews. |
| Quality | Try 0.75–0.85 for web images, then review sharpness and file size before publishing. |
Compression workflow
Resize very large originals before compressing, choose WebP for modern pages when compatibility is acceptable, and keep PNG when transparency must be preserved. Always keep the original image before replacing a production asset.
Recommended quality settings
For photos, try WebP or JPG around 0.8 quality and compare the output visually. For screenshots with small text, use a higher quality setting or PNG/WebP if readability matters. For transparent logos, avoid JPG because it removes transparency and can add an unwanted background.
Check the final image at the size where visitors will actually see it. A file can look acceptable as a small preview but show artifacts when opened full size.
Privacy and accuracy notes

- Compression runs through the browser canvas and keeps the selected file on your device.
- Converting PNG with transparency to JPG removes transparency.
- Always keep the original image if quality matters.

FAQ
Are my images uploaded to a server?
No. The compressor uses browser canvas processing on your device.
Which format should I choose?
Use WebP for modern web pages, JPG for photos where compatibility matters, and PNG when transparency is required.
Why is PNG sometimes larger after compression?
PNG is lossless and may not shrink much through canvas export, especially for photos.
Will compression reduce quality?
Lower quality settings and smaller dimensions can reduce detail, so review the preview before using the output.
