LemonSqueeze

Compress images to WebP/AVIF in the Webflow Designer and pick existing assets for CMS image fields instead of re-uploading.

LemonSqueeze speeds up image work in the Webflow Designer in two ways. 1) One-click compression Pick any images and LemonSqueeze compresses them locally to WebP or AVIF, kept under Webflow's 4 MB asset limit, then hands them straight to Webflow's own uploader. No more "upload failed" because a file was too large. High-quality resampling keeps images sharp, and an optional longest-edge cap (default 2000 px) avoids Webflow's resize warning. 2) Use existing assets in CMS image fields Webflow can't natively pick an already-uploaded asset for a CMS image field — you normally have to find and upload the original file again. LemonSqueeze adds an "Assets" button to CMS image fields (and the top mode bar) that opens a picker showing your Webflow assets and folders, loaded in the background. Click an image and it's placed into the field — no digging through your computer. What you need - The asset picker uses Webflow's official Data API. Add a Webflow site API token (scopes: Assets → Read and Sites → Read) once in the extension popup. It's stored locally in your browser only and used solely for api.webflow.com. - Compression runs entirely on your device — images never leave your browser. Note: Webflow stores CMS images separately from the Assets library, so the chosen asset's image is re-sent into the field's upload. You're spared finding and recompressing the source file; a literal link to the same asset entry isn't possible through Webflow's UI. Not affiliated with or endorsed by Webflow.
