Image Resizer guide
Resize images for web, email, and slides with a simple max width/height flow.
Open toolPrivacy
For supported workflows, files are processed locally in your browser and are not uploaded to SnapTools servers.
Overview
Social templates, slide decks, and CMS thumbnails all expect different pixel bounds. SnapTools keeps the original aspect ratio while fitting inside the maximum width and height you choose.
Upload a file, preview the resized output, and download a PNG without sending the image through our infrastructure.
How it works
We decode your file in-browser, draw it to an offscreen canvas at the computed dimensions, and export PNG bytes for download.
Benefits
Predictable dimensions help designers hand off assets without opening a desktop editor for quick tweaks.
Security & privacy
Your pixels never leave the tab for this workflow. Clear the download if you are on a shared workstation.
