Quality reduction ahead
PPM is uncompressed, meaning every bit of data is preserved. JPG uses lossy compression — some data is permanently discarded to reduce file size. At high quality settings the difference is usually imperceptible, but the original data cannot be recovered.
What compression artifacts to expect
JPG lossy compression can produce blockiness and mosquito noise around sharp edges. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.

Your PPM file is decoded — the compressed/stored pixel data is expanded into raw RGB pixels
Pixels are re-encoded using JPEG Image's lossy compression algorithm
Metadata (EXIF, ICC profiles) is transferred where JPG supports it
The JPG file is saved and ready for download

Frequently Asked Questions
Why won't my PPM file open?
PPM files may not open if your device lacks the right codec or application. Converting to JPG — a more widely supported format — usually resolves this. JPG (JPEG) uses lossy compression, making it ideal for photographs and complex images where small file size matters more than pixel-perfect quality.
Is it safe to convert PPM to JPG online?
Yes. CocoConvert encrypts your file via TLS, processes it on isolated servers in Germany, and permanently deletes it within 24 hours. Your files are never shared or analysed.
Will I lose quality converting PPM to JPG?
JPG lossy compression can produce blockiness and mosquito noise around sharp edges. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes. CocoConvert uses high-quality encoder defaults to preserve as much fidelity as possible.
How large can my PPM file be?
Free users can convert files up to 250 MB each. Pro users get a 5 GB limit per file, and Business API users have custom limits.
