FAQ
Does compression reduce quality?
The tool reduces file size while keeping visual quality as high as possible. You can control the balance using the quality slider.
What quality level should I use?
60–80% is a good balance for most uses. For web images where file size matters more, 40–60% works well. For print or archiving, use 80–100%.
Is this tool safe?
Yes. Your images are processed locally in your browser and never uploaded to any server.
How to use the image compressor
Large images slow down websites, increase data usage, and take longer to upload. This compressor reduces image file sizes by up to 90% while keeping quality high — no account needed, no upload to a server, everything runs in your browser.
- Upload your image — supports JPG, PNG, and WebP. Drag and drop or click to browse.
- Adjust compression — use the quality slider to balance file size versus visual quality. 75–85% is the recommended range for web images.
- Compare and download — review the before/after size, then download your compressed image.
Frequently asked questions
How much can I compress an image without losing quality?
At 80–85% quality, compression is usually invisible to the naked eye. Below 60% you may start to see artefacts, especially in photos with fine detail.
Does compression change my image dimensions?
No — this tool only reduces file size through compression. Dimensions (width × height) stay the same. Use the Image Resizer if you need to change dimensions.
Can I compress a PNG file?
Yes — PNG compression uses lossless methods, so the quality remains identical while file size is reduced.
What's the best quality setting for social media uploads?
70–80% is usually sufficient for Instagram, Facebook, and Twitter, which re-compress images anyway.
