Image Compressor for Brevo: Free Browser-Based Tool
→ Open the free Image CompressorBrowser-only, no signup, no upload. Output works with any Brevo campaign.
Brevo's built-in tools cover the basics, but the image compressor workflow often benefits from a dedicated, browser-only preprocessor before uploading. Reducing image weight before uploading keeps your email render-time fast and prevents Gmail clipping at 102 KB of HTML.
Why pre-process before uploading to Brevo
Brevo's drag-drop editor compresses on upload (lossy ~80% quality JPEG) — pre-compression with explicit quality settings produces more predictable results.
Step-by-step: image compression for Brevo
- Compress your image with the free in-browser tool below (uses MozJPEG + Squoosh-style optimization, no upload)
- Download the compressed file (typically 60-80% smaller than the original)
- Upload to Brevo's image library or media manager
- Insert into your campaign — render speed and total email weight both improve
