Frequently Asked Questions
How much can image compression shrink a file?
JPG photos typically drop 50-80% at 70-80% quality. WebP conversion can push that further with the same visual result.
Does compression destroy my image quality?
Done right, no. 70-80% JPG quality is visually identical on screen; you control the level with the slider.
Can I compress to a specific file size?
Yes — adjust quality, resolution and format until the live size preview matches your target (email, CMS, forum...).
Is a compressed image still printable?
For documents and scans yes; for large-format print keep quality above 90% to preserve detail.
How this tool works
Image compression is the art of making an image smaller without destroying the way it looks. Every photo you upload to a website, send by email or post on social media carries more data than it needs — and that extra weight slows everything down.
- Our compressor runs entirely in your browser. When you pick a photo, we decode it, remove redundant pixels and re-encode it into a leaner file — usually in under a second. No file is ever sent to a server.
- In lossy mode you choose the quality (lower quality means a smaller file). In lossless mode the file keeps every detail but still shrinks by re-encoding more efficiently. For GIFs we convert to WebP, which is dramatically lighter.
Why compressing your images matters
Page speed is now a ranking factor. A slow site ranks lower on Google, and visitors leave after three seconds of waiting. Images are the heaviest part of most pages — a set of optimised photos can cut load time by 70% or more.
Smaller images also save bandwidth (and mobile data), make an email attachment work when it otherwise wouldn't, and keep an online store or portfolio fast. Most of the time you can shrink a photo by 80–95% with no visible difference.
Pro tip: For web use, 75% quality is a safe starting point. If the photo has many fine details (text, logos), prefer lossless or 90% quality.
