Create crisp 40x40 pixel assets for tiny icons, favicons, and compact UI controls with precise resizing and fast local export.
Drag & drop or click to select your image (Max 20MB)
Supports JPG, PNG, GIF, WebP formats
Set exact dimensions, keep proportions, and export clean files without guesswork.
Preserve legibility at 40x40 by boosting contrast and simplifying forms, so micro icons remain recognizable on toolbars, menus, and quick-glance UI states.
Export a clean 40x40 asset for browser tabs, shortcuts, and mini badges, with file sizes small enough to load instantly across devices without slowing pages.
Preview the exact pixel grid while resizing, making it easy to see how each edge and corner will render at tiny scale before you download or export.
Downscale with optimized compression so the final file stays lightweight without introducing blur, ringing, or muddy colors in small shapes on light or dark backgrounds.
Great for status dots, app controls, and compact UI buttons where every pixel counts, spacing must be precise, and alignment stays consistent.
Create crisp assets that stay clean on high-DPI screens by starting with a larger source and resizing carefully to 40x40 without fuzziness on modern retina displays.
Upload a file, set 40x40 pixels, and export a tiny but sharp image in moments.
Drop in a source image and the preview appears instantly, so you can assess detail before shrinking to 40x40 and decide what to simplify.
Enter 40 for width and height or lock the ratio to keep proportions; the preview updates in real time for quick fine-tuning.
Export as PNG, JPG, or WebP to get a compact file ready for favicons, UI badges, or toolbar buttons with optional transparency.
Turn any image into a tiny 40x40 asset with clean edges and minimal weight, ideal for UI controls, favicons, and status indicators.
Resize to 40x40Quick answers to common questions about resizing images online.
40x40 is suited for micro UI elements like toolbar icons, status dots, small navigation buttons, and compact badges. It keeps interfaces clean when space is tight while still conveying meaning and hierarchy without crowding the layout.
Downscaling from a larger, clean source usually stays sharp. Blur happens when the original is already small or noisy. Use a high-contrast image and avoid thin lines to keep edges crisp, or redesign at small scale for the cleanest result.
PNG is ideal for tiny icons because it preserves sharp edges and supports transparency. WebP can be smaller with good quality. JPEG works for photos but may add artifacts around crisp shapes and flat colors, especially on line icons.
DPI does not change the pixel size on screen. For digital UI, DPI can be left alone. If you are exporting for print (rare at this size), DPI only affects physical print size, not clarity or sharpness, so use more pixels instead.
Simplify the design, remove fine texture, and emphasize bold shapes. Use solid colors and strong contrast. If text is required, keep it to one or two letters with generous spacing and test at actual size on a real screen.
Yes. Choose PNG or WebP and keep the background transparent. This is perfect for overlaying icons on different UI colors without visible boxes or unwanted edges, while keeping alignment clean and preventing halos in dark mode.
It is too small for a primary app icon, but great for in-app controls, status indicators, or navigation items. For main app icons, use larger sizes and scale down only when needed for small UI slots like settings or chips.
Most 40x40 files are just a few kilobytes, depending on format and complexity. Flat icons compress extremely well, while photos or gradients may be slightly larger but still very lightweight overall when you keep the palette simple.
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.
