Handles are too small on mobile
The 8 handles (4 corners + 4 edges) are 14×14px but have +8px padding around them, so the touch target is ~30×30. If precise tweaks are still hard, drag inside the rectangle to move the crop without resizing. A larger screen helps.
Locked ratio gives a strange size
The crop snaps to the largest rectangle that fits the chosen ratio at the current location. Switching ratios re-centers the crop, so set the ratio first, then fine-tune.
Crop looks awkward after rotating
When you rotate, the image is re-rasterized and the crop is reset. Apply rotation and flips first, then set the crop area.
What can canvas API actually do?
All cropping, rotation, and encoding goes through Canvas 2D API's
drawImage and toBlob. No external libraries or servers. Inputs: any format your browser supports; outputs: JPG / PNG / WebP.
Frequently Asked Questions
Are my photos uploaded to a server?
No. Cropping uses the canvas API in the browser only. Even the site operator cannot see your photos.
Safe for personal, family, and sensitive images.
What aspect-ratio presets are available?
Free / 1:1 (Instagram, profile) / 4:3 (cameras) / 16:9 (YouTube, landscape video) / 9:16 (Reels, TikTok) / 3:2 (DSLR, film) / 4:5 (Instagram portrait) — 7 presets.
When ratio is locked, the handles preserve the chosen ratio.
Recommended ratios per platform?
Instagram square = 1:1, Reels / Stories / TikTok / Shorts = 9:16, YouTube landscape = 16:9, Twitter (X) = 16:9 or 1:1, Facebook post = 1.91:1.
See the table above.
How does rotation work?
0 / 90 / 180 / 270 degrees + horizontal / vertical flip. Rotation is applied first, then you crop the rotated image.
Convenient when an iPhone photo opens sideways.
Does it handle very large images?
Normal photos (under 20MB) work on desktop and mobile. Very large images (50MB+ or 100+ megapixels) may slow due to memory limits.
Resize to 4000–5000px width first using the resize tool, then crop.
Does cropping reduce quality?
PNG and WebP are lossless; JPG uses the quality slider (default 90). Cropping extracts pixels exactly, so no extra quality loss.
Rotation may introduce slight blur via interpolation, but 90 / 180 / 270° rotations are pixel-aligned and lossless.
