Compress PNG to 2MB
Compress PNG to 2MB online free for forums and CMS uploads. Shrinks by reducing pixels and keeps transparency, in your browser: nothing is uploaded.
Drag & drop images here
Everything happens in your browser: your images are never uploaded anywhere. You can also just paste (Ctrl/Cmd+V) an image or an image URL.
MonsterConvert lowers quality as little as it can to get the file at or under this size.
Resize first (optional)
Some forms ask for a pixel size as well as a file size. Set it here and the file size is fitted after resizing.
How to compress a PNG image to 2MB
Three steps, all in your browser.
Add your image
Drag and drop your PNG (or any other image), click to browse, or paste it from your clipboard.
Check the 2MB target
The target is already set to 2MB. Change it if you need a different size.
Compress and download
Click Compress and download a file at 2MB or under, with as much quality kept as possible.
When you need 2MB
2MB is a typical upload limit for forums, CMS media libraries, and job portals. Most phone photos are several times bigger, so a light compression pass is often all it takes.
PNG is lossless, so it has no quality setting to lower. The only way to make a PNG smaller is to reduce its pixel dimensions, and transparency is kept. If the site you are uploading to accepts JPG, the JPG version reaches the same size with far less visible loss.
What to expect at 2MB
As a rough guide, a typical photo saved as a PNG at 2MB is about 1030 x 770 px. Logos, screenshots, and drawings with flat colors fit much more, and a photo saved as a JPG could be about 3270 x 2450 px at the same size.
Tips for getting to 2MB
- A PNG only reaches 2MB by having fewer pixels, so decide the smallest dimensions you can accept before compressing.
- If you don't need transparency and the destination accepts JPG, use the 2MB JPG page instead: the same size holds far more detail.
- Logos, icons, and screenshots with flat colors compress well as PNG. Photographs are the hard case.
Nothing uploaded
Compression happens in your browser using WebAssembly, so your photos and documents never touch a server.
Highest quality that fits
Instead of guessing a quality setting, it searches for the best one that keeps the file at 2MB or under.
Batch friendly
Drop in several images at once and compress them all to the same size in one go.

Frequently asked questions
Drop your PNG image into the box above and click Compress. MonsterConvert searches for the highest quality that still keeps the file at 2MB or under, and only shrinks the pixel dimensions if the quality alone can't get there. Then download the result.
It will be 2MB or smaller, as close to it as the search can get, which keeps as much quality as possible. It won't be padded up to the exact size. If your image is already under 2MB, it is returned unchanged.
Very large or very detailed images sometimes can't get under a small target without shrinking a lot. When that happens the row tells you it got as close as it could instead of pretending it hit the target. Try cropping away unneeded parts first, or set a larger target size.
PNG stores every pixel without loss, so there is no quality dial to turn down. The file only gets smaller if it has fewer pixels, which is why the compressor reduces the image's width and height until it fits 2MB. Choose the 2MB JPG page instead if a JPG is acceptable: it reaches the same size with much less visible loss.
Modern phone photos are often 3 to 8MB, so yes for sites with a 2MB limit. The compressor lowers quality just enough, and leaves smaller files alone.
Usually very close. The changes at this size are mostly invisible at normal viewing distances, though you may notice differences when zooming in on fine detail.
Yes. Open "Resize first (optional)" under the size controls and set a fixed width, exact dimensions, or a percentage. The image is resized first, and the file size is then fitted to 2MB.
MonsterConvert uses 1 KB = 1,000 bytes, so the result stays under the limit whether a website counts a kilobyte as 1,000 or 1,024 bytes. The size shown next to your file uses the 1,024 convention, so it can look slightly lower than 2MB.
No. The image is compressed inside your browser using WebAssembly, so it never leaves your device. That makes it safe for ID photos and other private documents.
Yes. Turn on "Keep original dimensions" under the size controls. Only the quality changes then, so the image may end up a little over 2MB if the quality floor isn't enough.
