Compress Image to 100KB or Less
Shrink photos reliably below a size you set, such as 100KB, 200KB or 500KB. Quality is lowered first, and if that is not enough, dimensions are reduced step by step.
Target size
How to use
When it helps
Job applications, exam registrations, school portals and government forms often ask for photos under 100KB or 200KB. Regular compressors only let you change quality, so hitting the limit takes several tries.
This tool starts from the target size and finds the highest quality that fits under it. If quality alone is not enough for a large photo, it reduces the dimensions step by step until it fits. The result is always at or below your target.
If the form also sets a size (for example, 300px wide), enter it as the max dimension. Shrinking the dimensions first leaves room for better quality at the same file size.
FAQ
Will it really be under 100KB?
Yes. Quality and dimensions are reduced together until the file is under the target. You can check each file size in the list.
What if the quality drops too much?
Enter the required size (for example, 600px) as the max dimension. Removing unneeded resolution lets more quality remain.
Are KB and KiB different?
This tool counts 1KB as 1024 bytes. Some sites use 1000 bytes, so if you need to be exact, set the target 2 to 3% lower.
Can I use PNG?
PNG has no quality setting, so it is hard to hit an exact size. JPG is the safest choice for uploads.
Are my files uploaded to a server?
No. Everything runs inside your browser, and your files never leave your device.
