Frequently asked questions
- How do I compress an image online for free?
- Open FreeKitHub’s Image Compressor, add your file, set quality (and format if needed), then compress and download. It’s free and runs in your browser.
- Do you upload my images?
- No. Compression happens locally in your browser. Files never leave your device — 0 bytes uploaded.
- Will compressing reduce image quality?
- Lower quality settings reduce file size and can soften detail. Start with a medium setting and compare the preview before downloading.
- Can I compress to exactly 200 KB?
- Yes — use Target max size (KB) or the 20 / 50 / 100 / 200 KB presets. The tool adjusts quality to stay under your limit. A dedicated Compress to Exact KB page is coming soon.
- Which formats are supported?
- Input: JPEG, PNG, WebP, GIF, and BMP. Output: JPEG, WebP, or PNG.
- Is PNG harder to compress than JPG?
- Often yes. PNG is lossless and may stay large; converting photos to JPG or WebP can yield smaller files. Use Image Converter if you need a format change first.
- Can I compress images for email?
- Yes. Compress here, check the resulting size, and attach. Use a target KB preset if your mail system has a size limit.
