What is the Image Resizer?
ToolsPopper's Image Resizer scales photos to exact width and height in pixels. Upload an image, set your target dimensions, optionally lock aspect ratio so proportions stay correct, preview the result, and download a PNG — no desktop software required.
Resizing happens on a canvas in your browser. Files are never uploaded to ToolsPopper, so profile pictures, product shots, and scanned documents remain private.
When to resize images online
- Social media specs — hit exact pixel requirements for banners and profile photos
- Web and app assets — export icons and thumbnails at precise dimensions
- Print and documents — scale scans to fit forms or slide decks
- Email signatures — shrink oversized logos before embedding
How the Image Resizer works
When you pick a file, the tool reads its natural width and height and fills the dimension fields. Change width or height manually, or enable Lock aspect ratio so editing one dimension updates the other proportionally. Click Resize to render on canvas and download the output as PNG.
