Compress to the exact size you need

Set a target in KB or pick a preset, and the tool reduces quality (and dimensions only if needed) to get your image as close to that size as possible while keeping it sharp. Perfect for upload limits on forms, job and government portals, and email.

Private, on-device compression

Your image is compressed locally in your browser and never uploaded. For whole folders or thousands of photos at once, the native Shrinkpad for Mac app does it in bulk, offline.

Frequently asked

How do I compress an image to a specific size?

Drop your image, then type a target size in KB (or pick a preset like 100 KB or 1 MB). The tool gets as close to that size as possible while keeping the quality high.

Are my images uploaded?

No. Everything is compressed locally in your browser on your device, so nothing is uploaded and it works offline.

Why compress to an exact size?

Forms, job portals, exam sites and email systems often set a maximum file size. Compressing to a target lets your photo pass those limits.

Can I compress several images to the same size?

Yes. Drop multiple images and each is compressed to the target, then download them individually or as a zip.

How do I do this for a whole folder?

For entire folders and thousands of files at once, Shrinkpad for Mac compresses them all, offline, with a one-time purchase.
