About this tool
Hit any file size limit on the first try
Job portals, exam and government applications, visa forms and many websites reject images over a strict limit, often 20 KB, 50 KB, 100 KB or 200 KB. Guessing at quality settings in an image editor wastes time and usually ends in an image that's either too big or much blurrier than necessary.
This tool searches for the highest quality that fits under your target. If even low quality isn't enough, it reduces the dimensions step by step until the file fits, so you always get the sharpest possible result within the limit. Each file shows the final size, the quality used and any change in dimensions.
Exact target size
Type any size in KB or pick 20, 50, 100, 200, 500 KB or 1 MB.
Best quality that fits
Quality is searched automatically; dimensions shrink only if they must.
Batch ready
Bring every photo for a form under the limit in one go.
HEIC friendly
iPhone photos are converted and compressed in one step.
FAQ
Frequently asked questions
How do I compress a photo to 20 KB?
Enter 20 as the target size, drop in your photo and download the result. For very small targets the photo may also be scaled down, and the new dimensions are shown.
Why is my image smaller than the target?
If the image already fits at high quality, it isn't padded out. The tool stops at quality 95, as anything higher adds size without visible benefit.
My form also requires exact dimensions. What should I do?
Crop or resize first with the Image Cropper or Resize Image tool, then compress here. You can also set a maximum width or height on this page.
Should I choose JPG or WebP?
Choose JPG for forms and portals, since they almost always accept it. WebP gives better quality at the same size, but not every site accepts it.
Are my files uploaded anywhere?
No. This tool runs entirely in your browser using JavaScript. Your files and text never leave your device, so it's safe for private or confidential work.
