Millimeter Precision for Small Prints
Dial in tiny physical sizes and keep details sharp for labels, badges, and small-format outputs.
Millimeter Precision
Set tiny width and height values in millimeters for precise labels, badges, and packaging inserts that must fit tight spaces. This keeps trims accurate when placement is tight.
Small-Format Accuracy
Ideal for ID photos, price tags, and product decals where a few millimeters make a visible difference in fit. This accuracy reduces reprints and wasted materials.
DPI-Aware Scaling
Choose DPI to keep small prints crisp and readable, avoiding fuzzy text or soft lines on miniature outputs. Higher DPI protects fine details.
Controlled Cropping
Lock aspect ratio and adjust composition to keep faces, logos, or barcodes centered within tiny dimensions. It prevents key elements from being cut off at print size.
Consistent Batch Sizing
Resize multiple assets to matching millimeter specs to keep sets of stickers or labels uniform across a run. Uniform sizing is critical for die-cut sheets.
Lightweight Export Options
Pick JPG or PNG for compatibility, or WebP for smaller files when sharing proofs and drafts. PNG is best when you need crisp edges on small graphics.

Millimeter Resize FAQ
Tips and answers for accurate MM sizing and small-format printing.
Millimeters provide finer control for very small formats where a few millimeters affect fit. It is useful for labels, stickers, and ID photos that must match strict templates. This precision helps avoid trimming or alignment problems.
For small prints, 300 DPI is a safe baseline, and 450 to 600 DPI can help preserve fine details like thin text or barcodes. Higher DPI increases file size but improves clarity. Use higher values when clarity matters more than size.
Start with a high-resolution image and avoid heavy upscaling. Lock the aspect ratio and preview the output so text and edges remain crisp at the final millimeter size. If text looks soft, increase DPI or reduce the physical size slightly.
The tool resizes to your dimensions while preserving the aspect ratio when locked. If your source and target ratios differ, you can adjust the crop preview to keep key details visible. Use the preview to keep the subject centered.
Yes. Labels and stickers often require specific proportions. Locking the ratio prevents distortion and keeps logos or text from stretching when you change size. It also keeps die-cut shapes aligned to the artwork.
Absolutely. Enter any millimeter width and height to match a template or die line. The tool converts the values into the correct pixel dimensions for export. This keeps the printed output aligned to your production specs.
PNG is best for sharp edges and transparency, while JPG works for photos. If your printer accepts WebP, it can reduce file size without major quality loss. For tiny text, PNG often preserves clarity better than JPG.
Yes. Enter the required millimeter dimensions and set a suitable DPI. Use the preview to position faces correctly before downloading the final file. This helps meet passport or badge specifications without extra cropping.
Yes. The resizer is free to use with no registration, watermarks, or hidden limits.
