How to compress an image to under 100 KB
Job portals, visa applications, and upload forms often reject photos over 100 KB. Set that target and the compressor automatically adjusts quality and, when needed, pixel dimensions to find a result that fits.
Step by step
Open the image compressor
Start the free image compressor — no account needed.
Add your image
Drop in the image you need to shrink; supported inputs are JPEG, PNG, WebP, and AVIF.
Set the 100 KB target
Enter 100 KB as the target size per image, then choose WebP or JPEG for the compressed output.
Choose the maximum long edge
Keep the 4,096 px default or lower it when the form also expects small image dimensions.
Compress, verify, and download
Run the compressor, confirm the result is at or below 100 KB, then save it for the form that rejected the original.
Tips that save a second try
If the compressor cannot reach 100 KB, crop unneeded background first or use a larger target instead of assuming an oversized result will pass.
The target-size compressor exports WebP and JPEG; use the image converter when another format matters more than the byte ceiling.
Keep the original file — compress a copy, so you can redo it if a portal wants a different limit.
Common questions
Why do upload forms reject images over 100 KB?
Many government and job portals cap file sizes to keep their storage and review systems fast. The limit is about file size, not image quality — a well-compressed photo passes and still looks fine.
Will compressing to 100 KB make my photo blurry?
It can, especially for detailed images or very small targets. Inspect the downloaded result before submitting it, and use a larger target when the form allows one.
