How to Reduce Image File Size
Photos that are too big get rejected by upload forms and bounce back from email. Here is how to reduce an image's file size without a noticeable drop in quality.
Two ways to make an image smaller
There are two levers: compression (lowering quality slightly to save space) and resizing (reducing the pixel dimensions). Doing a bit of both usually cuts a photo to a fraction of its size with no visible difference.
Reduce file size step by step
- Open the image compressor and drop in your photo or a whole batch.
- Lower the quality to around 70 to 80 percent, which is usually indistinguishable from the original.
- Optionally set a maximum width to shrink the dimensions too.
- Download the smaller file. Everything runs on your device, nothing is uploaded.
Hit a specific limit
If a form says "max 2 MB," compress, check the new size, and nudge the quality down until you are under it. Converting to WebP gets you the smallest file of all.
