Crop Photo Online
Precise crop by aspect ratio for any platform. Processing runs on our own server, your files never go to the cloud.
Crop a photo by ratio
Drag the frame to pick the area. The aspect ratio is locked by your choice below.
Which ratio for which platform
- 1:1 (square), Instagram feed, avatars, listing thumbnails, product thumbnails
- 4:5, vertical Instagram post, best for the feed
- 9:16, Stories, Reels, TikTok, YouTube Shorts
- 16:9, YouTube cover, video, covers for Telegram channels
- 3:4, vertical frame for catalogues and marketplaces
- 4:3, classic horizontal ratio, ID photos
- Custom, set the ratio manually, for example 21:9 for wide banners
How to use it
- Upload a photo
- Pick an aspect ratio
- Drag the frame and resize it to hit exactly the area you need
- Click Crop
FAQ
Is quality lost?
If the source was JPG, saving the result applies normal JPG compression (no visible loss). PNG and WebP stay lossless.
What is the output format?
The same as the input: JPG → JPG, PNG → PNG, WebP → WebP.
Can I rotate too?
For now it is crop by ratio only. To rotate, use Photoshop or your system tools.
Any limits?
Up to 25 MB per file, 30 files per minute, 200 per day per IP.

Which ratios and sizes each platform expects
The aspect ratio decides how your listing looks in search results, while the pixel size decides how sharp it stays when a buyer zooms in. Amazon expects the product to fill at least 85 percent of the frame and wants the longest side at 1600 pixels or more so that zoom is enabled, with 2000x2000 as a safe working size. eBay accepts a 1:1 square and recommends at least 1600 pixels on the longest side. Etsy displays listings at 4:3 in the grid but crops the first image to a square in several places, so keep the subject centred. Shopify themes are usually built around either 1:1 or 4:5, and mixing both in one collection breaks the grid.
Social platforms follow their own rules. A vertical 4:5 post takes the most screen height in the feed without being cropped. Stories, Reels and short vertical video need 9:16 at 1080x1920. Video covers and channel headers use 16:9 at 1280x720 or above. Email banners and website heroes usually run 3:2 or a wide 21:9.
The practical approach: shoot with margin around the subject, keep one master file at full resolution, and cut a separate crop for every destination. That way you never stretch an already cropped frame.
Cropping without losing quality or cutting off what matters
The core rule for product photos is that the item should fill the frame without touching its edges. Leave 5 to 10 percent of clear margin on every side. That breathing room is insurance, because platforms lay their own elements on top of your image: a discount badge in a corner, a wishlist button, a price tag, a profile icon in stories, and in the feed the edges get trimmed again to fit the device.
Reserve extra room at the bottom for vertical video. The lowest 250 to 300 pixels of a 1920 frame sit under captions, buttons and interface bars, so no logo or text belongs there. For a catalogue shot the safe zone is simpler: subject centred, with slightly more space above than below so the product does not look like it is sinking.
Cropping itself does not degrade an image. You discard pixels, the remaining ones are untouched. Loss appears later, when the cropped fragment is stretched back up to the required size. So always crop from the largest original you have, then check the result: if the short side falls below 1000 pixels, the frame is already too weak for a marketplace. Reshoot or use a wider composition rather than faking resolution.
Resizing: scaling down, scaling up, interpolation and file weight
Scaling down and scaling up are fundamentally different operations. When you reduce an image the software averages neighbouring pixels, there is plenty of information, and the result is almost always clean. When you enlarge, pixels have to be invented, which produces softness, mushy edges and stair-stepping along contours. The practical ceiling for a conventional algorithm is roughly 150 to 200 percent, beyond that you need a dedicated upscaler.
The interpolation method matters. Bilinear is fast but smears fine detail. Bicubic keeps edges crisper and suits photographs. Lanczos preserves the most micro detail when reducing heavily, though it can leave a faint halo along high contrast boundaries, for example on a white background around a dark product.
After any reduction the shot looks softer than the original, because micro contrast has been averaged away. Sharpening therefore belongs at the very end, applied at the final size and applied moderately: oversharpening reads on a listing page as a dirty outline and a white fringe around the item.
File weight does not fall linearly. Halving each side quarters the area, and a JPG usually drops 3 to 5 times. For a product card, 300 to 600 kilobytes at 1500x2000 is a sensible target, sharp enough and fast to load.
Common cropping mistakes and how to avoid them
Clipping the product. The most expensive error: a shoe toe cut off, a bag handle running past the edge, a bottle cap sliced away. In a thumbnail it reads as a defect and kills the click rate. Check all four edges before you save, not after the listing goes live.
A tilted horizon. A table, shelf or wall running a couple of degrees off makes the whole card look amateur. Cropping does not fix it. Straighten first, then crop, otherwise the rotation will eat even more usable area.
An inconsistent catalogue. When some photos are square and others vertical, and the product sits at a different scale in each, the grid falls apart. Fix one template: one ratio, one margin, one product scale, and hold it across the whole range.
Cropping from a preview. Working from a downsized copy or a screenshot guarantees mush. Only ever crop the original.
An off-centre subject. The item pushed against one edge with no compositional reason. Place it centrally or on a third, but do it the same way every time.
Repeated re-saving. Every open-crop-save cycle in JPG adds artefacts. Do all your edits in one pass and save once.
