Why image files are so large
A modern phone photo often has 12 megapixels or more and weighs 3–6 MB. That is far more than a screen needs: a website image rarely has to be wider than 1,600–2,000 pixels, and a picture shown in a chat even less. On top of that, cameras save at high quality settings that keep details nobody can see once the image is displayed.
Step 1: Pick the right format
The format matters more than any slider. Photos belong in JPG or WebP; PNG is lossless and best for screenshots, logos and graphics with transparency. Simply converting a photo saved as PNG to JPG or WebP can shrink it by more than half. Not sure which to use? Read our comparison of JPG, PNG, WebP and AVIF.
Step 2: Reduce the dimensions
Resizing is the most effective step. Halving the width and height leaves a quarter of the pixels – and roughly a quarter of the data. Use Resize Image to set the width you actually need; the height follows automatically, so nothing is stretched.
Step 3: Lower the quality a little
Open Compress Image, choose JPG or WebP and start at around 80% quality. Compare the result with the original: at 75–85% most photos look identical while the file is a fraction of the size. Graphics with fine text may need a higher value.
- Websites and blogs: 75–85% quality, 1,200–2,000 px wide
- Email and chat: 70–80% quality, 1,280–1,600 px wide
- Print: keep the full resolution and use 90% or more
Compress many images at once
For galleries, product catalogs or holiday photos, the Bulk Image Processor applies the same size, format and quality to up to 100 images and gives you a single ZIP. For websites, converting to WebP typically saves another 25–35% compared with JPG.
Your photos stay private
All IMGWE image tools run in your browser. Your photos are processed on your own device and never uploaded, so you can compress personal pictures and confidential screenshots without worrying about where they end up.
