Image Compressor
Make PNG, JPG, WebP, AVIF and GIF files smaller, with a quality slider and lossy or lossless mode.
- Add up to 10 images
- Pick a mode and quality
- Compress and download each result
Lossy discards fine detail for a much smaller file (best for photos). Lossless keeps every pixel and only removes redundant data.
Only used in lossy mode. Lower means a smaller file and more visible artefacts; 70–80 is usually a good balance.
Frequently asked questions
- Lossy compression discards some image data to get much smaller file sizes — usually not visible to the eye at moderate settings, but technically not identical to the original. Lossless compression only strips redundant data, so the image is pixel-for-pixel unchanged, at the cost of a smaller size reduction.
- PNG, JPG/JPEG, WebP, AVIF and GIF are all supported — upload any mix of these and each is compressed with settings appropriate to its format.
- At the default quality slider setting, the difference is generally invisible to the eye. Push the slider lower for smaller files at a visible quality cost — you can compare the before/after size and preview before downloading.
- Yes, batch upload up to the tool’s file limit and each image is compressed individually, with its own before/after size shown.
- Compression focuses on pixel data; some metadata may be stripped as a side effect of re-encoding, which is generally desirable for images you’re about to publish online (it removes camera/location details you likely don’t want to share).
