Frequently Asked Questions
Is it really free?
Yes. Compress as many images as you want at no cost. There are no daily limits, no watermarks, and no premium tier holding back features. Bulk compression, quality controls, and ZIP downloads are all included free for everyone, for personal projects and commercial client work alike.
Do I need to sign up?
No signup or account is needed. Just open the page and start compressing immediately. Your images are processed locally in your browser, so nothing is ever uploaded to a server and you can use the tool completely anonymously on any device.
Are my images private and safe?
Yes. Compression happens entirely on your device — your images are never uploaded anywhere. Open your browser's Network tab while compressing and you'll see zero image data leaving your computer. Your originals stay exactly where they are: on your own device.
How do I compress an image to exactly 50KB or 100KB?
Use the target-size option and enter 50KB or 100KB. The tool automatically adjusts the quality to hit your exact size, which is perfect for government forms, job portals, and exam applications that enforce strict file-size limits on uploads. No trial and error needed.
Will compression reduce my image quality?
Smart compression removes invisible data first, so size reductions of 60-80% usually look identical to the original. Use the quality slider and preview to find your ideal balance. For photos, JPG at 70-80% quality is the sweet spot. Zoom into the preview to compare fine details before downloading.
Can I compress multiple images at once?
Yes, bulk compression is fully supported. Drop in dozens of images, compress them all with one click, and download the results as a single ZIP file. This is ideal for photographers, bloggers, and anyone optimizing images for a whole website.
