How to compress an image to a specific size
- Set the target. Click 20, 50, 100, 200 or 500 KB or 1 MB, or type any size in KB. Choose Quality instead if you just want a smaller file without an exact limit.
- Drop the images. Each one is compressed right away. The list shows the old and new size, the saving in percent and the final pixel size.
- Download each file, or all of them as a ZIP.
How the target size is reached
The compressor tries JPG or WebP quality levels between 92 and 40 and keeps the highest quality that stays under your limit. If even quality 40 is too large, it reduces the pixel size step by step instead of lowering the quality further, because a slightly smaller image looks much better than a heavily compressed one. The result is always the sharpest image that fits.
Typical size limits
- 20 to 50 KB: signatures and photos on government and exam forms, many job portals and university applications.
- 100 to 200 KB: profile pictures, online shop product images and visa photo uploads (the US visa form allows up to 240 KB).
- 500 KB to 1 MB: images in emails and website photos that should still look sharp on large screens.
Example
A 4032 × 3024 phone photo of 3.1 MB with a target of 100 KB comes out at about 1300 × 975 pixels and quality 70, around 97 KB. With a target of 500 KB it keeps 2600 pixels in width at quality 80. Set Maximum width to 1920 px if you prefer a fixed pixel size for a website.
JPG or WebP?
JPG is accepted everywhere, so it is the right choice for forms and email. WebP is about 25 to 35 percent smaller at the same quality and is supported by all modern browsers, which makes it ideal for websites. PNG files are converted too: transparent areas become white in JPG and stay transparent in WebP.
Private by design
All compression happens in your browser with the built-in image encoder, so your photos are never uploaded. That also makes it fast: there is no upload or download wait, even for large batches.
Frequently asked questions
How do I compress a photo to 50 KB?
Click 50 KB, then drop the photo. The tool lowers the quality and, if needed, the pixel size until the file is just under 50 KB, and shows the final size before you download it.
Will the compressed image lose quality?
Some quality is always traded for size, but the compressor keeps the highest quality that fits your target and shrinks the dimensions before it goes below quality 40, so results stay clean.
Can I compress PNG images?
Yes. PNG images are saved as JPG or WebP, which are far smaller for photos. Choose WebP to keep transparency; JPG fills transparent areas with white.
Is there a limit on the number of images?
No. Drop as many as you like; they are processed one after another in your browser and can be downloaded together as a ZIP file.
Are my images uploaded to a server?
No. Compression runs entirely in your browser, nothing is sent anywhere and nothing is stored.
Why is the result bigger than my original?
The original was already compressed more strongly than your target needs. In that case simply keep the original file; the list marks these images.
