Image Compressor for AWS SES: Free Browser-Based Tool
→ Open the free Image CompressorBrowser-only, no signup, no upload. Output works with any AWS SES campaign.
AWS SES'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 AWS SES
SES does not host images. Pre-compressed assets at your CDN are critical at SES's typical high-volume sends.
Step-by-step: image compression for AWS SES

- Upload to AWS SES's image library or media manager
- Insert into your campaign — render speed and total email weight both improve
AWS SES-specific deliverability quirks to know
