Supported file formats
FileMorph converts between the formats below and compresses images to an exact target size (video too, by quality). Everything runs for free, with no account — or self-host it under AGPLv3. Pick any pair and start on the converter. Prefer operations over formats? See all tools.

Compress to a target size
FileMorph can shrink a JPEG or WebP image to an exact target size (for example 5 MB) using a binary search — useful for upload limits and email attachments. Try the compressor →

Need a format that isn't listed?
FileMorph is open source and the converter registry is plugin-based — new formats are added with a small Python module. Request one or contribute it on GitHub, or reach us via the contact form.
