When 5 MB makes sense
A 5 MB ceiling is useful when an upload allows a large file and you want a lighter copy without targeting aggressive compression.

A large ceiling can still re-encode
If the source is already below 5 MB, the original size becomes the effective ceiling. Keep the untouched original because processing creates a new encoded file.

Questions about 5 MB.
What the 5 MB ceiling means before you choose an image.
Will the compressed image stay under 5 MB?
Yes. A result is only shown as successful after its final Blob size has been checked at or below the effective 5 MB limit. If the original file is already smaller, the original file size becomes the effective ceiling.
Why can the result be smaller than exactly 5 MB?
5 MB is treated as a maximum, not a byte count that must be matched exactly. Image encoders produce discrete results, so the best valid output may land below the limit.
What happens if my original image is under 5MB?
The tool uses the smaller of 5 MB and the original file size as its effective ceiling. It will not report success for an output larger than the source.
Is a 5MB result identical to the original?
No guarantee of bit-for-bit or metadata preservation is made. The browser decodes and re-encodes the pixels, so the downloaded file is a processed copy even when the visual change is small.
Are my images uploaded or stored?
No. Your original and processed images stay inside your browser and are never uploaded to our server. Refreshing or closing the page clears the working image data from the browser. Files you download remain on your device until you delete them.
