Crop PNG Images Online
Trim any PNG to the frame you want with free or locked aspect ratios. Transparency is preserved pixel for pixel, nothing is uploaded, and every crop runs in your browser.
How to Crop a PNG in Three Steps
Drop your PNG in, drag the crop handles or lock a ratio, then export as PNG to keep transparency. Results download instantly with no upload, no signup, and no watermark.
Step 1
Add PNG
Drag in a PNG or click to browse; transparent logos and screenshots are supported.
Step 2
Set Frame
Drag the handles to choose the area, or lock 1:1, 4:3, 16:9, and more.
Step 3
Download PNG
Keep PNG as the output and save the cropped file with transparency intact.
Crop PNG Files to Any Frame While Keeping Transparency Intact
Every PNG arrives with more picture than you need. Logo exports carry a margin of empty space, screenshots include window chrome and desktop clutter, and sprite sheets pack dozens of frames side by side. Cropping is the operation that removes the pixels outside the frame you actually want, and it is different from resizing: no pixel inside the selection is resampled, so nothing softens. For PNG the stakes are higher, because the transparent border around a logo or sticker is part of the asset, and a careless crop can either waste that padding or destroy the alpha channel entirely.
This cropper loads your file into the browser, renders it on a canvas, and writes back only the region you selected. Transparent and semi-transparent pixels keep their exact alpha values, so a trimmed logo still drops cleanly onto any background color. You can drag the handles freely, or lock the selection to 1:1, 4:3, 16:9, 3:4, 9:16, or the original proportions when a platform is strict about shape. Output stays PNG by default for lossless quality, with JPG and WebP available whenever file size matters more.
Typical uses cluster around three needs. Tightening a logo or icon comes first: trimming the transparent padding around artwork makes it sit flush in a header, signature, or app bar without an invisible margin nudging it off center. Exact output dimensions matter just as often, because avatars, marketplace listings, and CMS templates frequently demand a fixed pixel frame, and cropping a PNG to size directly in the browser avoids a round trip through desktop software. Transparent assets deserve special mention, since stickers, print-on-demand artwork, scanned signatures, and website sprites all have to be cropped without turning see-through edges into a solid white box.
Cropping runs entirely on your device, so no file is uploaded and nothing is stored on a server. That makes it safe for confidential mockups, client logos, and unreleased designs. There is no account, no watermark, and no daily limit, and you can work through several images in one session, downloading each finished crop the moment it is ready. It also keeps working after the page has loaded, so a poor connection never interrupts a quick trim.
Cropping changes framing, not weight or pixel dimensions. If the result is still too heavy, follow up with a PNG compressor; if it needs a different pixel size, the resizer is the next stop. Start by framing what matters and keep PNG as the output whenever transparency counts.
Keep Transparency
The alpha channel is preserved, so cropped logos and stickers stay genuinely see-through.
Aspect Ratios
Lock 1:1, 4:3, 16:9, 3:4, 9:16, or original, or crop freely by hand.
Exact Crop Size
Drag the handles to any frame and the tool crops at full resolution without resampling.
PNG Output
Export as PNG for lossless quality, or switch to JPG or WebP when needed.
Batch Friendly
Crop several images in one session and download each result the moment it is ready.
Nothing Uploaded
All cropping happens locally in your browser, so private artwork never reaches a server.
FAQ
Frequently Asked Questions
Keep the output format set to PNG and crop as usual. The tool reads the alpha channel and writes every selected pixel back with its original transparency, so see-through areas stay see-through instead of being flattened to white.
No. Transparent and semi-transparent pixels inside your selection are preserved exactly. Transparency is only lost if you export as JPG, which has no alpha channel and must fill the background with a solid color.
Drag the crop handles to the region you want, then use the aspect ratio list to lock the shape you need. The crop is taken from the original pixels, so matching a required frame does not involve any resampling or quality loss.
Yes. Pick 1:1 for a square crop or 16:9 for widescreen, and the selection locks to those proportions while keeping the alpha channel. Both shapes are common for profile pictures, app icons, and video thumbnails.
No. Cropping only discards pixels outside your selection; the pixels inside are copied unchanged, with no resampling and no recompression. The saved file is a lossless PNG that looks identical to the framed region of the original.
Usually yes, because fewer pixels remain to store. The reduction depends on how much you trim and how detailed the remaining area is, so a logo loses more weight than a busy photograph after the same crop.
No. The entire crop is computed in your browser with the Canvas API. Your file never leaves the device, is never stored anywhere, and cannot be intercepted in transit, which keeps client work private.
You can drop in PNG, JPG, WebP, SVG, and other browser-supported images, then export the crop as PNG, JPG, or WebP. Choose PNG for transparency and lossless output, or WebP when you need a smaller transparent file.
Yes. Add multiple images in one session and crop them one after another, downloading each finished file as soon as it is ready. There is no daily cap on how many you process.
Yes. It is completely free with no signup, no watermark, and no usage limit. Once the page has loaded it keeps working even without a connection, so you can crop images anywhere.
