To make an image smaller, drop it here, choose a quality level and download a lighter file that looks the same at normal viewing size. Compression runs in your browser, costs nothing and needs no account.
Photos from a phone or camera are usually far larger than any screen needs. Compressing saves the picture again with file size as the goal, so pages load faster and attachments fit under upload limits.
How to compress images
- Drag your images, or a whole folder of them, onto the drop zone.
- Keep the default quality of 75, or move it up or down.
- Click Compress.
- Download each file on its own, or take them all as one ZIP.
Picking a quality level
The quality setting applies to JPG and WebP. It runs from 1 to 100 and trades file size against detail: lower numbers give smaller files and a rougher picture.
For photos on a website or in an email, aim for 75 to 85. The file gets much smaller, and the loss is hard to spot unless you zoom in. Choose 90 or more for images that will be edited again or printed.
Below about 60, flaws start to show. Smooth areas such as a clear sky break into blocks, and sharp edges pick up faint halos. The quickest way to decide is to run one photo at two settings, then compare the sizes and the look side by side.
PNG and the other formats
Because PNG is lossless, the only thing compression can do is store the same pixels more efficiently. Expect modest savings. That is fine for what PNG does best: screenshots, logos and flat-color graphics, especially those with transparent areas.
A photo saved as PNG is a different case. It stays large however well it is packed, and changing the format is what makes it small. Turning it into JPG, or converting it to WebP, brings the size down sharply.
Still GIF, BMP and TIFF files are accepted as well. For animations, a short video clip normally weighs far less than a GIF.
Compressing a whole folder
Because compression runs on your own device, there is no batch cap and no daily allowance. Drop the folder, let it finish, and download the results one by one or as a single ZIP. Speed depends on your computer or phone, so a large folder takes longer on an older laptop.
When a shop or blog needs several steps, a pipeline can resize, compress and rename every photo in one run. Pipelines are free to try on up to 3 files, and Pro runs them on up to 500. For one big job without a subscription, credits work too: one credit covers 25 files, and credits never expire. Larger pipeline runs are processed on our servers in Germany and deleted automatically within two hours.
Where your images go
They stay on your device. On this page, compression happens inside your browser, using the open-source JPG, PNG and WebP encoders that desktop image software also relies on. We never receive the files. It is free, without an account, for images up to 50 MB.
FAQ
Why is the new file bigger than the one I started with?
Your starting file was either squeezed hard already or saved at a quality below the one you picked. When that happens, stick with the original.
What happens if I compress the same JPG twice?
It loses a little more detail each time. Start from the original whenever you have it.
Will the width and height change?
No. The pixel dimensions stay exactly the same. To make the image smaller in pixels as well, resize it first.
Does compression keep the location and camera details?
No. EXIF data such as the GPS position and camera model is dropped, which also saves a few kilobytes. Keep the original if you will need the date taken later.
