Will compression make screenshot text blurry?
Use Best Quality (default ~95%) or PNG output to keep text sharp. JPG at 95% looks identical to source for screenshots; PNG is pixel-perfect.
Can I resize screenshots to App Store sizes?
Yes. Pick a preset for the target device — iPhone 6.5" (1242×2688), iPhone 6.7" (1290×2796), iPad 12.9" (2048×2732), and others. The tool resizes to exact App Store Connect dimensions.
Why no WebP or AVIF here?
App Store Connect only accepts PNG and JPG for screenshots. The other formats would be rejected on upload, so we hide them from this tool.
Are my images uploaded to your server?
No. All images are processed locally in your browser using JavaScript and WebAssembly. Your files never leave your device, and we have no infrastructure that could receive them.
Can I compress multiple images?
Yes. You can drop a batch of images (or an entire folder) and download the compressed results as a single ZIP file with the original folder structure preserved.
Which formats are supported?
JPG, PNG, WebP and AVIF are supported when available in your browser. The Auto mode picks the smallest modern format your browser can encode.
Can I compress images to a specific size?
Yes. Use the
Compress to KB tool to target 100KB, 200KB, 500KB, 1MB or any custom size.
Do I need an account?
No. There is no signup, no login, and no payment. The tool works as soon as the page loads.
