Why use Aback Images for compress to 10kb
Hits the limit precisely
Binary-searches the encoder quality to land just under your target, then reduces dimensions only if it must.
Minimum size too
Some forms reject files that are too small. Set a minimum and the JPG is padded safely to meet it.
Processed on your device
Your images are decoded, edited and encoded inside this browser tab by Web Workers. Nothing is uploaded to a server.
Shows its work
Each result reports the final quality, dimensions and how many attempts it took.

Frequently asked questions
Can I get exactly the target size?
Encoders produce whatever size the content needs at a given quality, so the result lands at or just below your target rather than exactly on it.
Why did the dimensions change?
If even the lowest quality is larger than your limit, the image is scaled down step by step until it fits. Turn off Shrink dimensions if you would rather keep the size and accept a larger file.
Are my images uploaded anywhere?
No. Processing happens inside your browser with WebAssembly and Web Workers. The site only downloads the app code and codecs; your files never leave your device. You can confirm this with the live upload counter on the tool, or in your browser's network panel.
Can I process many files at once?
Yes. Drop a whole selection or folder. Files are processed in parallel on several worker threads, each result can be downloaded on its own, and everything can be saved as one ZIP.
Is it free? Is there a file limit or watermark?
It is free with no account, no watermark and no daily limit. The only limit is your device's memory: very large images (over roughly 100 megapixels) may be refused to keep the tab from crashing.
