DM Imager
DM Imager
Resize, compress, and convert your images (JPG, PNG, WebP) right in your browser — by width, by exact dimensions, by percentage, or to hit a target file size. Nothing is uploaded to any server.
Why DM Imager
Precise Resize
Resize by width, by exact width & height, or by percentage — you decide exactly what you need.
Hit a Target File Size
Tell it the MB you want and DM Imager automatically finds the right quality and dimensions to get there.
WebP Conversion
Convert JPG/PNG to modern WebP (or vice versa) for smaller files and faster-loading pages.
100% Private
Everything runs locally in your browser. Your images are never uploaded anywhere.
How It Works
Drag & drop or click to select up to 20 images.
Pick a width, exact dimensions, a percentage, or a target file size in MB, plus your output format.
Download each image individually or grab them all at once as a .zip file.
FAQ
Is my image uploaded to a server?
No. DM Imager processes everything locally in your browser using the Canvas API. Your images never leave your device.
How does “Target File Size” work?
Enter the size in MB you want. DM Imager automatically tries different quality levels, and if needed, slightly reduces the image dimensions, until the output file is as close as possible to your target size (without going over).
Can I resize to an exact width and height?
Yes — choose “Exact Width & Height” mode, enter both values, and optionally lock the aspect ratio so the image isn’t stretched.
How many images can I process at once?
Up to 20 images per batch. You can download them individually or as a single .zip file.
