How to use Compress Image to 30KB
Add one or more images — the target is preset to 30 KB.

Why use it
Why use our Compress Image to 30KB tool
Room for a little more detail
30 KB gives noticeably cleaner skin tones and text than 20 KB, which helps when a form allows it.
Batch friendly
Photo, signature and a small ID scan can all be compressed in one go, each reported separately.
Change the target any time
Need 25 KB or 35 KB instead? Type it in or tap a quick size; every file re-compresses automatically.
Private by design
Your images are processed on your own device and never sent to a server.
FAQ
Frequently asked questions
When would I need a 30 KB image?
Some online applications and HR portals allow photos or documents up to about 30 KB. The exact number varies, so follow your form's own instructions.
Can I compress a scanned document to 30 KB?
Yes, as long as it is an image (JPG, PNG or WebP). Text stays readable best if you crop away margins first. For PDFs, use a PDF tool instead.
Why is the result 29.4 KB and not exactly 30 KB?
JPEG sizes jump in small steps, so the tool picks the best quality that is still under your limit. Being slightly below the limit is what forms require.
Does it work with PNG files?
Yes. PNG is lossless and can't be squeezed to a size, so PNGs are saved as JPG (or WebP if you choose) to reach 30 KB.
