Frequently Asked Questions
How do I crop an image online for free?
Drop a JPG, PNG or WebP image into the tool, drag the crop box or its corner handles to frame the area you want, and click Crop & Download. You can also type exact pixel values for X, Y, width and height.
How do I crop a photo to a square (1:1)?
Choose the 1:1 aspect ratio preset. The crop box is locked to a square, so resizing it from any corner keeps equal width and height — ideal for profile pictures and Instagram posts.
Does cropping reduce image quality?
Cropping itself removes pixels but does not resample the ones you keep. Saving as PNG is lossless; JPEG and WebP re-compress the image, so use a quality of 90% or higher if you want no visible difference.
Why is my photo rotated after uploading?
Phone cameras store orientation in EXIF metadata instead of rotating the pixels. This tool reads that EXIF orientation and displays the photo upright; if it still looks wrong, use the Rotate button before cropping.
Are my images uploaded to a server?
No. The image is decoded, cropped and encoded entirely in your browser using the Canvas API. Nothing is uploaded or stored, so private photos and screenshots never leave your device.
Does cropping remove EXIF metadata like GPS location?
Yes. The cropped file is re-encoded from the canvas, which writes only pixel data. Camera model, GPS coordinates and other EXIF fields from the original photo are not copied to the download.
How to Crop an Image
- Load your image — drag a JPG, PNG, WebP or GIF file onto the drop area or click to browse.
- Pick an aspect ratio — keep it Free or lock it to 1:1, 4:3, 16:9, 9:16 or 3:2.
- Frame the subject — drag inside the box to move it, drag a corner to resize it, or focus the box and nudge it with the arrow keys (hold Shift for 10 px steps).
- Fine-tune — type exact X, Y, width and height values; they are real pixels of the original image, not screen pixels.
- Download — choose PNG, JPEG or WebP and save the cropped file.
Under the hood the photo is decoded with createImageBitmap, which applies the EXIF orientation written by phone cameras, so portrait shots are not shown sideways. The selected region is then drawn onto an off-screen canvas at full resolution and encoded in the format you choose. Because the output is re-encoded, EXIF metadata such as GPS coordinates is not carried over — a nice privacy bonus when sharing photos publicly.
Recommended Aspect Ratios for Social Media
Every platform crops uploads to its own frame. Cropping yourself first means you decide what stays in the picture instead of an automatic center crop cutting off heads or text.
| Use case | Ratio | Recommended size (px) |
|---|---|---|
| Instagram square post | 1:1 | 1080 × 1080 |
| Instagram portrait post | 4:5 | 1080 × 1350 |
| Instagram / TikTok Story, Reels, Shorts | 9:16 | 1080 × 1920 |
| YouTube thumbnail | 16:9 | 1280 × 720 |
| X (Twitter) in-feed image | 16:9 | 1600 × 900 |
| LinkedIn / Facebook link image | 1.91:1 | 1200 × 627 |
| Profile picture (most platforms) | 1:1 | 400 × 400 or larger |
| Classic photo print (4×6 in) | 3:2 | 1800 × 1200 |
For ratios without a preset (4:5 or 1.91:1), use Free mode and type the exact width and height, then resize the result to the final pixel size with the Image Resizer.
Cropping Tips and Gotchas
- Use the rule of thirds — the guide lines inside the crop box split it into a 3×3 grid; placing eyes or the horizon on a line usually looks more balanced than dead center.
- Crop before you resize — cropping keeps original pixels, so do it first and scale down afterwards for the sharpest result.
- Transparent PNGs — export as PNG or WebP to keep transparency. JPEG has no alpha channel, so transparent areas become white.
- Animated GIFs — only the first frame is cropped; the output is a still image.
- Very large photos — browsers limit canvas size (around 16,384 px per side on many devices). Huge panoramas may need to be cropped in smaller pieces.
Which Output Format Should You Choose?
Same as original is the safe default: a JPEG stays a JPEG and a PNG stays a PNG (GIFs are saved as PNG because browsers cannot encode GIF). Pick PNG for screenshots, diagrams, logos and anything with sharp text or transparency — it is lossless, but photos become large. Choose JPEG for photographs that will be emailed or uploaded to sites that do not accept WebP; a quality of 85–92% is visually identical to the original for most pictures. WebPproduces files roughly 25–35% smaller than JPEG at similar quality and supports transparency, making it the best choice for images on your own website. If you need an even smaller file after cropping, run the result through an optimizer instead of lowering the quality slider too far.
