Lossy JPEG gives smooth control over file size. Transparent areas are filled with white before encoding.

Will the downloaded file always match my MB number exactly?

We aim for that byte length by re-encoding under your cap, then padding after the image data (many apps ignore the padding). If the target is unrealistically small for the picture, you may see an error instead.

Can I use PNG or WebP uploads?

Yes. Common raster formats you can open in a browser usually work; the download is always JPEG.

Image to exact file size

One image at a time, up to 300.00 MB. Set a target size in megabytes; we re-encode to JPEG and align the file length to your number. Uploads up to 12 MB are free on the upload tier; larger files use credits.
