Free target-size image tool

Compress an image to 50 KB or less

A 50 KB limit is common in compact upload workflows, but the destination may also require a particular format and pixel size. This page sets the size ceiling for you. Add dimensions only when they are stated in the form, then compare the finished image with your original.

Where processing happens

JPG, PNG, and WebP stay in this browser by default. HEIC/HEIF files are uploaded to our server for conversion. No file is silently sent to the server if browser processing fails.

Browser-processed files stay on this device. Server-processed files are uploaded for this request; the tool does not create a stored download session.

Tip: Use “within bounds” when pixels may shrink further. Exact canvas and center crop preserve the specified dimensions even if the KB cap cannot be met.

Measured example

What happened to one test image at 50 KB?

This reproducible, textured illustration was 589.1 KB (603,220 bytes) at 1200 × 800 pixels. A measured JPG export with a 50 KB cap produced 49.2 KB (50,371 bytes) at 1032 × 688 pixels. It met the cap of 51,200 bytes.

The sample used the server encoder. The default browser encoder, other images, and other browsers can produce different sizes and quality. Check your own result in the tool.

Check all of the form's rules

  • If the form says JPG, keep JPG selected. WebP can be smaller, but a destination that accepts only JPG will reject it.
  • For a portrait, use within bounds if the stated pixels are a maximum. Select exact canvas only when the form requires an exact width and height.
  • A signature or logo often compresses more cleanly after cropping broad margins. Keep a copy of the uncompressed original in case you need to retry.

Where your images are processed

JPG, PNG, and WebP process in your browser by default. HEIC and HEIF go to our server for conversion, and you can choose server processing for other files. The tool accepts up to eight images, 10 MB each and 40 MB in total. It labels any above-cap output as best effort, so check the displayed bytes and pixels before submitting it elsewhere.

Questions about the 50 KB limit

Does 50 KB mean exactly 50,000 bytes?

No. This tool treats 50 KB as a maximum of 51,200 bytes and may produce a smaller file. Confirm how your destination defines KB if it uses a different rule.

Can I process an iPhone HEIC photo here?

Yes, HEIC and HEIF use the server conversion path. JPG, PNG, and WebP process in your browser by default; the page labels the processing location before you start.
