Generation loss — quality may degrade
JPEG uses lossy compression, and so does WEBM. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
Some metadata may not survive
Your JPEG file may contain EXIF, IPTC, XMP, ICC metadata. WEBM has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
Color depth reduction: 24-bit → 10-bit
JPEG stores up to 24 bits per channel, but WEBM supports only 10 bits. You may notice banding in smooth gradients (like sky or skin tones) where subtle color transitions are lost.
What compression artifacts to expect
WEBM lossy compression can produce blockiness (VP8), blurring (VP9/AV1). 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.

Frequently Asked Questions
Why won't my JPEG file open?
JPEG files may not open if your device lacks the right codec or application. Converting to WEBM — a more widely supported format — usually resolves this. WebM is Google's open media format based on VP8/VP9/AV1 codecs, optimised for web streaming.
Is it safe to convert JPEG to WEBM 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 JPEG to WEBM?
JPEG uses lossy compression, and so does WEBM. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible. CocoConvert uses high-quality encoder defaults to preserve as much fidelity as possible.
How large can my JPEG 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.
Can I convert JPEG to WEBM on my phone?
Absolutely. CocoConvert works in any modern browser — iOS Safari, Android Chrome, and all desktop browsers. No app required.
