Your images never leave your browser
All processing happens locally on your device. Nothing is uploaded to a server, stored, or tracked.
Many uploaders cap photos at 1 MB without hurting quality much. Squeeze a large photo down to a single megabyte for social posts and galleries with quality search.
How it works
Why compress images to 1000 KB?
Many uploaders cap photos at 1 MB without hurting quality much. Squeeze a large photo down to a single megabyte for social posts and galleries with quality search.
How target-size compression works
This tool re-encodes your image repeatedly, searching for the highest quality that still fits under 1000 KB. Choose the output format, JPG, WebP, PNG or AVIF, and the best match wins.
Which output format should I pick?
JPG is the safest default for photos. WebP keeps transparency and compresses well. PNG suits graphics and text. AVIF gives the smallest files in modern browsers.
Is compression private?
Compressing to 1 MB runs entirely on your device. Your image is processed locally and never uploaded.
Batch compress images to 1MB
Compress a batch of photos to under 1 MB each for uploaders and galleries. Free, private, batch ZIP, processed entirely in your browser.
Frequently asked questions
Will a 1MB image still look sharp?
Yes. Most photos under 1MB look great on screen, especially after resizing to display size or at balanced quality.
Should I resize before compressing to 1MB
Yes if the photo is larger than display size. Shrink to needed pixels first, then compress to 1MB for best sharpness at smallest size. Start with resize to 1920x1080 then compress.
Can I batch compress many images to 1MB without uploading
Yes. Add your folder, pick 1MB target, and compress together. Each image is searched locally for best quality under 1MB and you can download a ZIP.
