Crop APNG

Crop an APNG Down to the Region You Want

This page opens the xconvert Photo Editor with the Crop tab selected. You pick a .apng or .png file, drag a selection box over the preview (or type exact W x H values under "Crop area"), and download the trimmed result. It is a single-frame editor: it works on the first frame of the file you give it, and "Save as" has no APNG option — "Same as original" saves an edited APNG as a still PNG, and the editor says so when the file opens ("Animated APNG: an edit here keeps only the first frame."). Downloaded without an edit, the file is your original, animation intact. So if you upload a genuinely animated APNG, what you get back is a cropped still, not a shorter animation. That is the honest headline, and the rest of this page tells you what to do in either case.

That still trips nobody up on a static .apng — and a lot of .apng files are static. A single-image APNG that came out of a converter is a plain PNG with no animation chunks at all, so cropping it here is exactly the right tool. For a multi-frame source, jump to the "keep the animation" section below.

How to Crop an APNG

1. Choose Your APNG Files: Drag and drop APNG images onto the page or click "Choose APNG files" — up to 50 at once. The first photo opens in the editor and the rest line up as thumbnails below it; with two or more photos open, "Add more" adds files to the same batch.
2. Set the Crop: In Crop, pick an "Aspect ratio" ("Free", "Original", 1:1, 4:3, 16:9 and more) or a platform size, then drag the box on the photo or type its width and height under "Crop area". "Shape" switches between "Rectangle" and "Circle (avatar)". The crop applies to every photo in the batch.
3. Pick the Output Format (Optional): "Save as" keeps "Same as original" or saves as JPG, PNG, WebP or another format. For JPG, WebP and AVIF output, the "Quality" slider (40–100) trades file size against detail. Resize, Crop, Rotate and Flip all work in the same session, and "Undo" steps back.
4. Download: Click the Download button, which names the output format (for example "Download PNG"), for one photo, or "Download all (.zip)" for a batch — "Download one by one" saves the files separately. APNG files are processed right in your browser, so they are not uploaded. No sign-up, no watermark.

What Each Save Format Keeps

What happens to a frame with a transparent background in each "Save as" format:

The practical rule: PNG for anything with soft edges or a knocked-out background, JPG only for a fully opaque photographic crop, TIFF when a print or archive workflow demands a TIFF master (it is written lossless, Deflate-compressed).

If You Need the Whole Animation, Not One Frame

Cropping every frame of an APNG at identical coordinates is not something this editor does. Nothing on xconvert crops an animation frame-by-frame today. What is available, and does preserve the animation, is Compress APNG: it is a server-side route that re-extracts every frame at the real duration, reassembles them with apngasm, and honours the Image resolution controls — so scaling an animated APNG, and rotating or flipping it with the per-file buttons on the file card, all keep the loop intact. Files there are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared or made public.

If you can live without APNG, the other two escape hatches are APNG to GIF, which keeps motion at the cost of a 256-colour palette and 1-bit transparency, and APNG to MP4, which keeps motion and gains temporal compression but drops the alpha channel entirely (no video container stores it).

Frequently Asked Questions

Does cropping here keep my APNG animated?

No. The editor works on the first frame of the file, and none of the ten "Save as" formats is an animated PNG. We checked this against a purpose-built 3-frame APNG (200x120, one coloured circle per frame): after the frame was drawn and saved back out as PNG, only frame 1's circle was present, and the saved file contained just IHDR, IDAT and IEND chunks — no acTL, so it is a static PNG by definition. Use Compress APNG if the loop has to survive.

Which frame do I actually get?

Frame 1. In our test the first frame's content was on the canvas and the second and third frames' content was absent, even after leaving the image on screen for longer than a full animation cycle. There is no frame-picker on this page, so you cannot ask for frame 12 of 30.

Will cropping lose my transparency?

Only if you save as JPG or BMP, which have no alpha: transparent areas become white (for JPG the editor offers a "Keep PNG" button). PNG, TIFF, WebP and AVIF keep the alpha channel; GIF keeps only on/off transparency, so soft edges become hard-edged.

Can I crop an APNG to a circle or a rounded rectangle?

A circle, yes: under "Shape", pick "Circle (avatar)". The result is saved as a square with transparent corners, and "Save as" switches to PNG if the chosen format has no alpha. There is no rounded-rectangle shape; for that, crop to a rectangle here and apply the mask in an editor that does layer masks.

Can I crop several APNGs at once?

Yes — drop up to 50 APNG files at once (a mixed batch works too). The crop region (or aspect-ratio preset) you set applies to every file in the batch; "Download all (.zip)" saves every cropped result in one ZIP, or use "Download one by one" to save them separately.

Should I crop first or resize first?

Crop first. Cropping throws away pixels at the source resolution; resizing afterwards only has to resample the region you kept, so no detail is spent on pixels you are about to discard. Both tabs act on the same working image, so you can set the crop and then switch to the Resize tab without re-uploading.

Why is my saved BMP or TIFF bigger than the source APNG?

BMP is uncompressed: the BMP this page writes is 24-bit, three bytes per pixel plus a small header, flattened onto white. The TIFF is compressed losslessly (Deflate), so it is far smaller than a BMP but can still come out larger than the PNG. If you want a lossless save that is also small, choose PNG.

Does a .apng file that is really just a still PNG work here?

Yes, and that is the ideal case for this page. An APNG with no acTL chunk is a plain PNG wearing a different extension — every decoder reads it as a normal still, so cropping and saving it as PNG is a straight lossless round-trip with nothing lost. Our own single-image APNG conversions produce exactly that kind of file.

Where does APNG still play if I convert it instead of cropping it?

APNG animates natively in Chrome 59+, Edge 79+, Firefox 3+, Safari 8+ (including iOS Safari 8+), Opera 46+ and Samsung Internet 7.2+ — about 96% of global browsers according to caniuse. Anything that does not support it, such as Internet Explorer or Opera Mini, displays the first frame as a static PNG rather than showing a broken image. APNG is now formally part of the PNG specification: the W3C published PNG Third Edition as a Recommendation on 24 June 2025, with the acTL, fcTL and fdAT chunks and the image/apng media type defined in the standard itself.
