Direct quality control for one clean export
Lossy compression trades some visual detail for a smaller file. Fine texture, lettering, gradients, and hard contrast reveal artifacts before flat areas do.
Processing stays in this browser. Start from the master and export once, because repeatedly compressing a downloaded copy compounds blocks, ringing, and color damage.
How to compress without repeated damage
- 1
Choose the highest-quality source
Load the master or first-generation export instead of an already compressed copy.
- 2
Select format and quality
Compare JPEG and WebP when the destination accepts both, then inspect detailed areas at 100%.
- 3
Download one final derivative
Confirm visual quality and file size before using the export; return to the master for later changes.

Quality control is not a KB guarantee
- This direct-quality tool does not guarantee a specific file-size result.
- PNG is lossless and may remain large for photographs.
- Compression cannot restore a low-quality or previously damaged source.
Image compression questions
Which is smaller, JPEG or WebP?
WebP is often smaller at similar visual quality, but compatibility and image content matter. Compare both when allowed.
Does lower quality change dimensions?
No. It changes encoding detail; width and height stay the same.
Is the source uploaded?
No. Compression runs locally in this browser.
