Deploy larger Workers — up to 64 MiB for both free and paid plans
You can now deploy Workers with larger dependencies, heavier frameworks, and more code without hitting size limits.
When you deploy a Worker, Wrangler bundles your code and compresses it before uploading. Previously, Cloudflare checked that compressed size and rejected deploys over 3 MB (Free) or 10 MB (Paid). That limit has been removed. Cloudflare now only checks the uncompressed size of your bundle, which is 64 MiB across all plans.
To check your Worker's bundle size before deploying:
wrangler deploy --outdir bundled/ --dry-runTotal Upload: 259.61 KiB / gzip: 47.23 KiBThe Total Upload value is your uncompressed bundle size. This is what counts against the 64 MiB limit. The gzip value is shown for reference but is no longer a limit.
For more information, refer to the Worker size limits documentation.
