Frequently Asked Questions
Can I compress a JPG to exactly 100 KB?
Yes. The tool targets 100 KB by progressively reducing JPEG quality. In most cases it hits the target precisely. If the image is already very small or heavily compressed, it will reach the minimum viable quality and show you the best achievable size.
Does the image get uploaded to a server?
No. All compression happens locally in your browser using JavaScript. Your image is never sent to any server, so your photos remain completely private.
Can I convert a JPG to JPEG and reduce it to 100 KB at the same time?
Yes. JPG and JPEG are the same format — the tool compresses either and outputs a standard .jpg file under 100 KB. PNG and WebP images are also converted to JPG during compression.
How do I reduce a JPG size below 100 KB without losing quality?
The compressor uses a binary-search algorithm to find the highest JPEG quality setting that still fits within 100 KB. This means the output quality is as high as mathematically possible for that file size target.
Can I set a custom target other than 100 KB?
Yes. After the initial compression you can type any size (e.g. 50 KB, 200 KB) in the target field and click Apply to recompress to that size.
