Why Choose CompressKaro?
Your Files Stay With You
Everything happens in your browser, on your own phone or computer. Your documents, photos and videos are never uploaded, so nobody else gets a copy, and you don't spend data sending them anywhere.
Exact Size Limits
Type the limit the form or app gives you, like 20 KB for a photo, 500 KB for a PDF or 25 MB for a video. The file comes out under it, with the best quality that fits.
Full Offline Support
After you use a tool once, it is saved on your device, so you can keep compressing photos, PDFs and videos without an internet connection.
Frequently Asked Questions
Is CompressKaro safe to use for government forms and KYC?
Yes. Everything happens inside your browser on your own device, so documents like Aadhaar, PAN card scans, signatures and photos are never uploaded or stored anywhere.
How does the exact size work?
You type the limit (for example 20 KB for a photo or 25 MB for a video). The tool tries different quality levels on your device and keeps the clearest version that is still under your limit. It counts the strict way (1 KB = 1,000 bytes), so the file passes on every site.
Does this tool store a copy of my documents or photos?
No. There is no server that receives your files. They stay in your browser's memory while you work and are gone when you close the tab.
Can I use this compressor offline?
Yes, after you have used a tool once with the internet on. The tool is then saved on your device, so it keeps working without a connection.
Are there any file limits or watermarks?
No. You can compress as many files as you want. There are no signup gates, no premium limits, and the tool does not add any watermarks to your outputs.
