Find a PNG's File Size
Drop a PNG (or any image) to see its exact size in bytes, kilobytes and megabytes. It's measured in your browser, so nothing uploads — a quick check before an email or upload that has a size limit.

Bytes vs. KB vs. MB
The report shows the human-friendly size (KB or MB) and the exact byte count, because upload limits are sometimes specified in one and sometimes the other. Note that 1 KB here means 1,024 bytes (the binary convention most operating systems use), so a "500 KB max" field that counts 1,000-byte kilobytes may treat the file as slightly larger.
Too big?
If a PNG is over a limit, Compress re-encodes it smaller, and Resize cuts the pixel dimensions — usually the biggest lever on file size.
FAQ
How do I find out how many KB a PNG is?
Drop it above and click Check size — the KB and MB size plus the exact byte count appear immediately, read in your browser.
Why does my OS show a slightly different size?
Operating systems sometimes report "size on disk" (rounded up to the filesystem block size) rather than the true byte count. This tool shows the actual bytes.
