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.
Why compress your images?
Large image files slow down web pages, blow past email attachment limits, and eat up storage on your phone or site. Compressing trims the file size while keeping the image looking essentially the same — a photo gallery that loads in a second instead of ten, or a batch of product photos small enough to upload without a timeout.
This tool handles PNG, JPG, WebP, AVIF and GIF with a quality slider so you control exactly how much size reduction you're trading for image fidelity, plus a lossless mode for when you need the pixels untouched. Batch up to 10 images at once and compare the before/after size on each before downloading.
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).
