Compress Image
Make JPG, PNG and WebP images smaller — even down to a specific file size like under 100 KB. Free, private and right in your browser, with batch support.
Compress to an exact target size
Need a photo under 100 KB for a form, a forum, or a job application? Switch the mode to Target size and type a number in kilobytes. ImageBloom automatically searches for the highest quality that still fits under your limit, so you get the smallest acceptable file without guesswork.
How to compress an image
1. Click Open the compressor above. 2. Drop your images (any mix of JPG, PNG or WebP). 3. Use Quality for a simple slider, or Target size to hit an exact KB limit. 4. Optionally resize to smaller dimensions for even bigger savings. 5. Download individually, all at once, or as a ZIP.
Tips for the smallest files
Converting to WebP usually gives the best size at a given quality. Resizing a huge photo (for example capping the width at 1600 px) is often the single biggest saving. For photographs, a quality of 75–85% looks great while being far smaller than the original.
