Lossless vs lossy compression
PNG images are compressed losslessly — no quality is lost. JPEG and WebP images are compressed at 92% quality (near-lossless) — visually indistinguishable from the original at a fraction of the size.
How to use
- Drop one or more images onto the dropzone, or click to browse.
- Compression happens automatically.
- Click Download next to any image, or Download all to save all compressed images at once.
All compression runs in your browser using the Canvas API — no images are uploaded to any server.
Frequently Asked Questions
- How much will my files be compressed?
- Compression results vary. Already-optimised JPEGs may see little improvement. Unoptimised PNG screenshots often compress significantly.
- Is JPEG compression lossy?
- Technically yes, but at 92% quality the difference is visually imperceptible for most images.
