Image Compressor
100% in your browser — nothing is uploadedUpload forms that reject anything over 1 MB, email attachments that bounce, web pages that crawl — oversized images cause all of it. Pick a target size, drop your images, and each is compressed on your device to fit under that ceiling, with the before/after size shown so you can see exactly what you saved.
Compression resizes oversized dimensions and tunes encoding quality together to hit the target with the least visible damage. For photos, the result at 0.5–1 MB is usually indistinguishable from the original at normal viewing sizes.
How to use the image compressor
- Pick a maximum size — 0.2 MB for strict forms, 1 MB for general use.
- Drop one or more JPG, PNG, or WebP images.
- Download each compressed file; the size reduction is shown per image.
Frequently asked questions
How much quality do I lose?
At 1 MB, typically none you can see at normal viewing sizes. At 0.2 MB, fine textures may soften on large photos. The tool resizes very large dimensions first (capped at 4096px on the long edge), which alone solves most oversize problems invisibly.
Are my photos uploaded?
No — compression runs in a web worker in your own browser. Personal photos never leave your device.
Why is my PNG screenshot still large?
PNG is lossless, which limits how far it can shrink. If the screenshot doesn't need transparency, convert it to JPG or WebP first — the combination compresses dramatically further.
