Compress images to a smaller size
Compress by a quality level, or ask for a target size per image. When a target cannot be reached honestly (for example lossless PNG), the result says so instead of pretending.

JPG · PNG · WebP — files stay on your device
How to use it
- Pick a mode: quality level, or target size in KB per image.
- For target mode choose an output format — JPG or WebP can hit a size target; PNG is lossless and may not.
- Press Compress, check each row's before/after size, then download files or a ZIP.
Limits & formats
Up to 20 images per batch, each up to 20 MB and 25 megapixels. PNG is lossless: without changing format its size may barely drop, and the tool will tell you instead of faking a smaller file. Quality re-encoding always loses some detail — check previews.
