What it does
Big images are slow to upload and often too large for a form or an email. This tool makes a smaller copy of each image and shows how much it saved:
JPG and WebP are saved again at the Quality you set: 75 by default, on a scale of 1 to 100.
PNG keeps its sharp edges and transparency, with its colours reduced to at most 256.
Save as keeps the format or changes it to JPG or WebP. GIF and BMP images come out as PNG, and AVIF as WebP.
Also shrink to at most, under More options, makes the longest side at most that many pixels too. Images are never enlarged.
Each file’s card shows its size before and after, and the box below the files shows the total saving, such as “You saved 3.1 MB” and “That’s 62% smaller”.
How to use it
Drop your images on the box, paste them, or select Choose files. Select “Try a sample” to see two example images.
Move the Quality slider or change Save as. Every image is compressed at once, and again when you change a setting.
Select Download on a card to save one image, or Download all to save them together in a ZIP file.
Press Ctrl+Enter (⌘+Enter on a Mac) to compress every image again, or Esc to stop the ones still working.
Good to know
Each image can be up to 50 MB and 50 megapixels, and you can add up to 20 images at once.
The tool reads JPG, PNG, WebP, AVIF, GIF and BMP still images. Animated images and HEIC photos aren’t supported yet.
When a new file isn’t smaller than the original, the tool still makes it, and its card says so.
Transparent areas stay transparent in PNG and WebP. JPG has no transparency, so they turn white.
Files are named after the original with -compressed added, such as photo-compressed.jpg.
Saving as WebP needs Chrome, Edge or Firefox. Safari opens WebP images but can’t save them, so choose JPG there.
Privacy
Your images are processed on your device: the tool runs in your browser and doesn’t upload them. The new image is made from the pixels alone, so camera details and location data from the original are always removed.
Frequently asked questions
Will my images look worse?
At the default Quality of 75, most photos look the same at normal viewing size; zoomed in, fine detail is a little softer. Lower values make smaller files, with softer detail and blocky edges in JPG and WebP. A PNG keeps its sharp edges, but with fewer colours a smooth gradient can show bands. Compare the result with the original before you replace it.
What does Quality do to a PNG?
PNG has no quality setting of its own, so for PNG output Quality sets how many colours the new file keeps. From 75 up it keeps up to 256 colours; below 75 it keeps fewer: up to 171 at 50 and 3 at 1. An image with no more colours than that keeps every colour exactly, and its card says exact. With Reduce PNG colours turned off under More options, the PNG keeps every pixel and Quality doesn't change it.
Which format makes the smallest file?
For photos, WebP is usually the smallest, then JPG. For screenshots, logos and drawings with few colours, a PNG with reduced colours is often smaller than either, and keeps text sharp. Each card shows the size before and after, so you can try Save as with your own images and compare.
Why did my PNG get bigger?
The tool writes a new file from the image's pixels. A PNG that was already saved with few colours, or squeezed hard by another tool, can come back the same size or a little larger. The card then says Not smaller and what to try. You can still download it, or keep the original.
What happens to location and camera data?
It's always removed. The new image is made from the pixels alone, so camera details, the date and any GPS location in the original are left out. When a JPG had a location, its card says Location data removed.
Are my images uploaded?
No. Your images are compressed by your browser, on your device, and they aren't sent anywhere. There's no account or sign-up.
