Best use cases for image cropping
- Crop an AI render, product shot, screenshot, or photo into a clean social, thumbnail, avatar, or website frame.

Why this image cropper is different
- Aspect-ratio presets match real publishing jobs instead of forcing raw coordinate entry.
- Local canvas processing keeps client screenshots, private photos, and AI drafts off upload-based editors.
- It pairs directly with resize, compression, and metadata cleaning workflows.
Task-focused FAQ
Should I crop before resizing?
Yes. Crop to the right composition first, then resize to exact pixel dimensions.
What crop should I use for Instagram feed?
Use 1:1 for square posts or 4:5 for portrait feed posts. Use 9:16 for Stories and Reels covers.
Will cropping remove metadata?
Exporting through the browser may drop some metadata, but use Image Metadata Cleaner when privacy cleanup is required.
Frequently Asked Questions
When should I crop vs resize a GPT Image 2 / Midjourney output?
Crop when you want to keep the subject at native resolution but change aspect ratio or remove unwanted parts (signatures, artifacts, background). Resize when you need specific pixel dimensions for a platform upload. Crop preserves more source detail than a downscale + extend operation.
Can I crop to exact Instagram / TikTok / YouTube aspect ratios?
Yes — preset buttons for 1:1 (square), 4:5 (IG portrait), 9:16 (Reels/TikTok/Shorts), 16:9 (YouTube/landscape), 3:2 (standard photo). Or "Free" for manual ratio.
How do I crop a Midjourney 1:1 render down to 9:16 for Reels?
Upload the 1024×1024 Midjourney output, pick the 9:16 aspect preset, the tool snaps the crop rectangle to that ratio and you can slide it vertically to frame your subject. Output is lossless PNG at whatever pixel dimensions you kept — no upscaling artifacts from a forced resize.
Does the output lose quality?
Cropping is pixel-exact — no re-scaling. Output PNG is lossless. A 1024×1024 GPT Image or DALL-E PNG cropped to 512×512 drops ~4× in file size (area-proportional) with zero quality loss.
Does my AI render upload anywhere?
No. Canvas crop runs in-browser. Open DevTools Network tab — zero requests. Your GPT Image 2 / DALL-E / Midjourney output never leaves your device.
