Batch Settings
Some metadata may not survive
Your WEBP file may contain EXIF, 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
WEBP 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.
Sur un marché numérique en constante évolution, la capacité à adapter ses contenus est primordiale. Passer du format WEBP, souvent privilégié pour l'efficacité des images fixes sur le web, au format WEBM, idéal pour la vidéo de haute qualité avec une excellente compression, répond à un besoin croissant de polyvalence. Que vous soyez un professionnel du design, un éditeur de contenu ou un chercheur, cette conversion vous ouvre les portes de nouvelles opportunités pour diffuser vos messages de manière plus dynamique et engageante. Notre outil a été conçu pour simplifier ce processus, garantissant une transition fluide de vos animations ou séquences d'images vers un format vidéo largement compatible et performant, sans compromis sur la qualité visuelle. Transformez vos créations statiques en expériences animées captivantes, prêtes pour le partage et l'intégration sur diverses plateformes.
- Animations pour rapports annuels (entreprises françaises)
- Tutoriels didactiques pour plateformes académiques (universités suisses)
- Bannières publicitaires animées (agences belges)
Au Québec, où l'intégration de contenus multimédias dans les communications institutionnelles est en hausse, la conversion WEBP en WEBM est particulièrement utile pour les 'motion designers' afin d'optimiser les performances web des animations sans sacrifier la qualité visuelle.

Now for the details. WebP is Google's modern image format offering both lossy and lossless compression at 25-35% smaller sizes than JPG/PNG. WebM is Google's open media format based on VP8/VP9/AV1 codecs, optimised for web streaming. Converting between these two formats lets you convert between formats quickly.
Full Name: WEBP uses WebP Image, while WEBM uses WebM Video. Compression: WEBP uses Lossy & Lossless, while WEBM uses Lossy. Transparency: WEBP uses Yes, while WEBM uses —.
Your WEBP file is decoded and re-encoded as WEBM. 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.
Common misconception: ""My animated WEBP will stay animated after conversion"" — in reality, webm does not support animation. only a single frame will be saved. use webp or gif to preserve animation.
CocoConvert runs entirely online — no software to install, no account to create. Your files are encrypted during upload (TLS), processed on isolated servers in Germany, and permanently deleted after 24 hours. It works in Chrome, Safari, Firefox, Edge, and all mobile browsers.
Need to convert more than one file? Free users can do 5 per hour. Pro gets 100 per hour with files up to 5 GB each.
