Crop image
Crop images precisely — free or with a fixed aspect ratio (1:1, 16:9, 4:3, 3:2). Position via numeric input. Output as JPG, PNG or WebP.
About this tool
In shortCrop with aspect-lock and custom ratios — grabbable corner handles, locally in your browser.
Cropping is the digital version of scissors for images. You select a rectangular region of the original and keep only that area. Unlike scaling, no pixel is altered or interpolated — the pixels in the selected area are preserved byte-exact.
This tool crops images locally in your browser. The cropper offers eight grabbable handles (four corners plus four edge midpoints) with generous 28-pixel hit areas that work precisely even on touchscreens. You can drag the selection (drag inside), expand or shrink in any direction (corner handles for proportional, edge handles for one-axis), and nudge pixel-precise with arrow keys (Shift + arrow for 5% steps).
Aspect-ratio presets.Eight predefined ratios: Free (anything), 1:1 (square — Instagram posts, profile pictures), 4:3 (classic photo, old monitors), 3:2 (DSLR standard, application photos), 16:9 (widescreen, YouTube thumbnails), 9:16 (portrait, Reels, TikTok), 21:9 (ultrawide, banners), 2:3 (portrait photo, book covers).
Custom ratio.If no preset fits, click "Custom…" and enter any two numbers. The tool shows the resulting decimal ratio live (e.g. 1.618:1 for the golden ratio). Useful for platform-specific non-standard ratios — e.g. certain e-commerce templates or specialized print formats.
Rule of Thirds overlay.Four thin white lines divide the active crop into nine regions. The Rule of Thirds is one of the oldest composition guides in photography: important subjects should sit on these lines or their intersections, not at center. Helpful for portraits and landscapes.
Output dimensions.During selection the tool shows the output size live — both as a percent of the original and in absolute pixels. Example: with a 4000×3000 original and a crop covering 50% × 50%, the output is 2000×1500 px. Helps catch a too-small selection early.
Format choice.After cropping, pick the output format (JPG, PNG, WebP). JPG defaults to quality 85 — a solid all-purpose value. For maximum sharpness go up to 90; for smaller files down to 78.
