Supports JPG, PNG, GIF, WebP formats
Great for labels, packaging, and tiny prints where precision matters.
Set exact mm measurements for labels, stickers, and product guides. The tool converts millimeters to pixels precisely for accurate output.
Fine-tune tiny adjustments without rounding errors. Perfect for detailed layouts where a few millimeters can change alignment.
Match DPI to print requirements so small elements stay legible. Higher DPI keeps fine lines sharp at tiny sizes.
Generate consistent sizes for packaging, manuals, or CAD exports that require strict measurement compliance and accurate output ratios.
Jump between mm, cm, inch, and pixels while keeping the same scale. This makes verification easy across specs and tools.
Everything runs in-browser, so sensitive assets stay private and updates are instant. Download results without server delays.
Upload, set millimeters and DPI, then export precise files.
Add a JPG, PNG, or WebP file. The preview loads quickly so you can focus on millimeter settings.
Type the mm width and height, choose DPI, and lock the aspect ratio if the artwork must stay proportional.
Export the resized file when the dimensions look correct. Adjust and re-download without reuploading.
Perfect for labels and technical layouts. Set millimeter dimensions, choose DPI, and export exact-size files in seconds.
Resize in MMAnswers to common questions about millimeter sizing.
Millimeters are ideal for small items like labels, stickers, or detailed specifications where tiny changes matter. Centimeters are better for larger prints and general layouts.
DPI determines how many pixels are packed into each inch. Higher DPI produces more pixels for the same mm size, which improves sharpness but increases file size.
Yes. You can set small mm values and preview the output. For tiny labels, using a higher DPI helps keep text and line art readable.
Upscaling can soften details because new pixels are added. For critical print work, start with a larger source or reduce the target mm size to avoid blur.
Yes. Use the lock to preserve proportions. Adjusting one side will automatically update the other to prevent distortion.
PNG works well for sharp graphics and text, while JPG is suitable for photographic labels. Choose the format that matches your artwork and printer requirements.
Yes. The unit selector lets you switch to pixels and see the exact digital resolution. This is useful when adapting print assets for web or app displays.
Yes. Your files are processed in the browser and never uploaded. This keeps sensitive designs private and makes resizing fast.
Yes. You can resize and download images for free, with no signup required. Processing happens locally in your browser, so there are no usage caps or hidden fees.
No. All resizing and compression run in your browser. Files never leave your device and are not stored on our servers, keeping your images private.
