Three steps to publish-ready crops

Start with a single drop, lock the composition, then export pixel-perfect assets. The guide below highlights the controls that keep social covers, product cards, and print artwork consistent.

Frame

Choose the right ratio before you touch the crop. The canvas instantly resizes to fit.

Drag handles or pinch to zoom until the main subject fills the frame.
Pick from Instagram, YouTube, TikTok, Shopify, or your saved presets.
Need a custom size? Enter pixel values for width and height and lock the ratio.

Refine

Dial in composition with guides, snapping, and precise offsets.

Toggle Rule of thirds or Center guides to align horizon lines and logos.
Use arrow keys for single-pixel nudges — hold Shift for faster 10px jumps.
Adjust mask strength to see the bleed while keeping focus on the crop.

Export

Deliver ready-to-ship files with metadata and background options tailored to each channel.

Switch between PNG, JPG, and WebP while previewing estimated file size instantly.
Fill the background with brand colors or keep it transparent for layered design work.
Decide whether to retain EXIF data before handing assets off to clients or teammates.

Common questions

Frequently asked questions

Everything you need to know about using the crop tool effectively and troubleshooting common scenarios.

Does the cropper run entirely locally?

Yes, 100% client-side. All processing happens in your browser using Web Workers and Canvas API. Images never leave your device, ensuring complete privacy and instant performance.

Can I preserve EXIF metadata when exporting?

Absolutely. Enable the 'Keep metadata' toggle before export to embed original EXIF data (camera settings, GPS, timestamps) into JPEG and WebP files. PNG doesn't support EXIF by spec.

What's the maximum supported image size?

The tool handles up to 50 megapixels using a dynamic resolution pyramid for smooth preview. Export always uses original full-resolution pixels regardless of preview optimizations.

How do I reset to the original uncropped image?

Click the 'Reset' button in the canvas controls to instantly return to the initial full-size crop. Alternatively, use undo (⌘/Ctrl+Z) to step back through your editing history.

Can I export at a different resolution than the crop?

Yes! In the Size controls panel, choose 'Custom export size' and enter your target dimensions. The tool will resample using high-quality Lanczos interpolation while preserving your composition.

Will my work be saved if I close the browser?

Your current image, crop settings, presets, and history are auto-saved to IndexedDB. Reopen the tool and it automatically restores your previous session exactly as you left it.

How do I create a custom aspect ratio preset?

Set your desired width:height ratio, choose format/quality/DPI, then click 'Save preset'. Name it and it'll appear in the presets panel for instant reuse across sessions.

Why do my exports look slightly different from the preview?

The preview uses GPU-accelerated scaling for smooth 60fps interaction. Exports always use the original pixels with Lanczos resampling for maximum quality. Color profiles are converted to sRGB for consistency.

Can I use keyboard shortcuts to speed up my workflow?

Yes! Press ⌘/Ctrl+O to import, ⌘/Ctrl+E to export, ⌘/Ctrl+Z to undo, and arrow keys to nudge the crop by 1px (hold Shift for 10px). See the shortcuts panel for the full list.

Does the tool work offline after the first load?

Yes! The crop tool is a Progressive Web App (PWA) that caches all assets on first visit. Once loaded, it works completely offline with no internet connection required.
