100KBCompress image to 100KB
Quick answer
For forms or web images with a 100KB cap. Quality and resolution may change; check the actual file size and legibility before uploading.
3 numbered images + 1 damaged file. A real processing example.

Your finished images will appear here.
Check each image, its dimensions and file size before downloading.
Use this preset for registration photos or web images when the destination specifies a 100KB cap. Processing stays in your browser; check fine text, facial detail and the actual output size. This preset uses 100 KiB (102,400 bytes). If the destination uses decimal KB/MB, check its byte cap and use a lower custom target.
When to choose 100KB
Read the destination’s size, format and pixel requirements first. A 100KB target can suit small upload images, but meeting a file-size cap does not ensure readable text, sufficient pixels or acceptance.
Quality at 100KB
The result depends on the source content, output format and pixel count. Texture and dense text can suffer; the tool may lower resolution to approach the target, so inspect the output at a readable scale.
How it differs from generic compressors
Target mode tries different encoding qualities and may lower resolution. It reduces manual adjustment but cannot guarantee that every file meets the target; use the actual byte count and appearance to decide.
Frequently asked questions
There is no guarantee. The tool tries quality and resolution changes and reports the actual result. This 100KB preset uses 100 KiB (102,400 bytes); if the destination allows only 100,000 bytes, choose a lower custom target and check the actual output bytes.
It can. Dense text, fine lines and high-resolution photos need particular care. Inspect the output at its intended viewing size; if it is unclear, try a larger target or crop irrelevant areas first.
No. Compression runs locally in your browser, files are never uploaded, and it's free with no file-count limit.
