  2. See the file size displayed instantly in KB and MB.
  3. Compare against common limits — the tool shows whether your file passes the most common portal thresholds.
  4. If it fails — use the linked tools to compress, split, or convert your file to bring it under the limit.

Frequently asked questions

Does this tool upload my file?
No. The file size is read entirely by your browser without the file ever leaving your device. This tool accesses only the file's metadata, not its content.
Why do portals reject files that are close to the limit?
Many portals enforce limits on the raw binary file size, not the size shown in your operating system (which may use base-10 MB). A file showing 9.9 MB in Windows may exceed a "10 MB" limit on a portal using binary measurement. Aim to keep files 5–10% under the stated limit to be safe.
