How to compress an image to 2MB
- Select Choose files, or drop a JPG, PNG or WebP image on the box.
- The tool aims for under 2MB, which is 2,097,152 bytes here. It tests quality levels from 95 down to 40 percent and keeps the sharpest result that fits.
- If 40 percent is still too big, it shrinks the width and height by 15 percent at a time until the file fits.
- Select Download. The result ends in
-compressed, so your original is untouched.
Where a 2MB limit comes from
A 2MB limit is common for photo uploads on large forms, marketplaces and support tickets. A fresh phone photo of 4 to 8MB is the usual reason people land here.
What 2MB means in pixels
2MB is 2,097,152 bytes, or 16,777,216 bits. Divide that by the number of pixels and you get the bits each pixel can use. Photos look fine at about 1.5 bits per pixel or more, and the table shows how common sizes fare at 2MB.
| Picture size | Pixels | Bits per pixel | At 2MB |
|---|---|---|---|
| 640×480 | 307,200 | 55 | comfortable, the tool keeps all pixels |
| 1024×768 | 786,432 | 21 | comfortable, the tool keeps all pixels |
| 1600×1200 | 1,920,000 | 8.74 | comfortable, the tool keeps all pixels |
| 4000×3000 | 12,000,000 | 1.40 | fine for photos |
At 1.5 bits per pixel, 2MB holds a picture of about 3,862×2,897 pixels in a 4:3 shape (11,188,214 pixels). Two megabytes leaves plenty of room. A 12 megapixel photo normally needs only a mild quality drop to about 85 to 90 percent and keeps its full pixel size. Only very large images, such as 50 megapixel files, need shrinking.
Tips
- Most phone photos get under 2MB with no visible change at normal viewing size.
- HEIC photos from an iPhone are often accepted by nobody. Convert with HEIC to JPG first, then compress.
- If you need a much smaller file, try 500KB or the 1MB page.
