How to use Compress image
- 1
Choose your images, drag them onto the box, or paste a screenshot with Ctrl+V.
- 2
Pick a quality. 75–80% keeps photos looking the same while cutting their size a lot.
- 3
Optionally choose an output format. WebP and AVIF are usually much smaller than JPG.
- 4
Press "Compress images", then download each image or all of them as a ZIP.
What this tool does
Compress image reduces the file size of your pictures so they upload faster, fit email and form limits, and load quickly on websites. Pick a quality level and, if you like, a new format. The tool re-encodes each image with modern encoders and gives you the smaller files back.
Features
- Batch compression. Drop in a whole folder of photos and download them all as one ZIP.
- Four formats. JPG (MozJPEG), WebP and AVIF with a quality slider; PNG with lossless optimisation (OxiPNG).
- Format conversion. Turn heavy JPGs or PNGs into WebP or AVIF in the same step.
- Never bigger. If an image can't get smaller in its own format, you get the original back.
- Paste support. Paste a screenshot straight from the clipboard.
Limits
- Supported inputs: JPG, PNG, WebP and AVIF. For iPhone HEIC photos, use HEIC to JPG first.
- Animated GIF or WebP files are compressed as a still image (the first frame).
- Transparent images converted to JPG get a white background, because JPG has no transparency.
- AVIF encoding is slower than the other formats, especially for large photos on phones.
Where your file is processed
This tool works in your browser: your file is processed on your own device, so it isn't sent to our server for this tool. Some other tools on UtiloNest do use our server, and their pages say so.
Frequently asked questions
How much smaller will my images get?
It depends on the image. Phone photos saved as JPG often shrink by 40–70% at 75% quality with no visible difference. Converting the same photos to WebP or AVIF usually saves even more. PNG screenshots are optimised without any loss, which typically saves 10–40%.
Where is my file processed?
In your browser. This tool works on your own device, so the file isn't sent to our server for it.
Is there a limit on how many images I can compress?
No daily limit and no batch limit. Images are processed one at a time to keep memory use low, so even large batches work; they just take a little longer.
Why did an image stay the same size?
If the compressed version would be bigger than your original (for example an image that was already heavily compressed), we keep the original instead of handing you a larger file. The result shows how many images were already optimised.
Does compression remove the photo's location and camera data?
Yes. Re-encoding drops EXIF metadata such as GPS location, camera model and the date taken. That makes compressed photos safer to share online. The photo is turned the right way up first, so it won't come out sideways.
