Does cropping an AVIF reduce image quality?

Cropping discards the pixels outside the selected rectangle, but the kept region is re-encoded into a new AVIF — there is no block-aligned lossless crop path for AVIF the way jpegtran -crop exists for JPEG. At the cropper's default quality the re-encode loss is well below JPEG's because AVIF's AV1-derived intra-frame coding is much more efficient. For pixel-identical output, enable Lossless mode; the file will be larger but every kept pixel is preserved exactly.

Will alpha transparency be preserved when I crop?

Yes. AVIF supports a full 8-bit alpha channel (256 levels of transparency, identical to PNG-24) and the cropper preserves it. Logos, icons, and PNG-style transparent assets stay transparent in the cropped AVIF — no flattening, no white background. If your source has a wider alpha bit depth (rare), the output keeps the same alpha precision as the input.

What happens to HDR and 10- or 12-bit color when I crop?

If your source AVIF is 10- or 12-bit with an HDR transfer function (PQ or HLG, BT.2020 primaries), the cropper keeps the bit depth and color space by default — useful when the input is a screenshot from an HDR phone (recent iPhones and Pixels export HDR AVIFs) or a graded render. You can also explicitly set the Bit Depth in the options if you want to down-convert HDR to 8-bit SDR to maximize compatibility with older viewers.

Can I crop an animated AVIF?

Yes. Animated AVIFs (image sequences) crop frame-by-frame: the same X, Y, width, and height region is applied to every frame, and the output stays an animated AVIF. Frame count, frame rate, and loop behavior are preserved. If you only need a single still frame, Convert AVIF to PNG extracts one frame at a time.

Why is encoding the cropped AVIF taking longer than I expected?

AVIF uses AV1 intra-frame coding, which is roughly 5-10× slower to encode than JPEG and can be 40-50× slower than WebP at default speed settings. That's the tradeoff for the format's smaller file size. The cropper exposes a Compression Speed option — lower the speed (slower encode, smaller file) for archival or hero images; raise the speed (faster encode, slightly larger file) when you're batch-cropping hundreds of product shots and turnaround matters more than the last 5% of file-size savings.

Will every browser open the cropped AVIF?

As of May 2026, native AVIF decode is available in Chrome 85+, Firefox 93+, Edge 121+, and Safari 16.4+ — caniuse.com reports about 94% global support. Mainstream legacy environments that can't decode AVIF: IE 11, older Android WebView, and Safari before 16.4 on iOS 15 and earlier. If you need to support those, use the HTML element to serve AVIF first with a JPEG or WebP fallback, or Convert AVIF to JPG for a static fallback file.

Can I crop to a circle or rounded-corner shape?

Standard cropping is rectangular only — both AVIF and the cropper produce a solid rectangle of pixels (with optional alpha transparency). For a true rounded-corner or circular mask, use an image editor like Photopea (free, browser-based) or GIMP to apply the rounded shape after cropping, or use a CSS border-radius / clip-path on the rendered web page. For circular profile pictures on LinkedIn, Slack, Discord, or GitHub, a centred 1:1 square is sufficient — those platforms apply the round mask automatically when they display the avatar.

Why is my cropped AVIF still larger than I expected?

Cropping removes pixels proportionally — a 4000×3000 source cropped to 1080×1080 keeps roughly 9% of the pixel area, and the file usually shrinks 70-85%. But final size also depends on output quality, bit depth, and the visual complexity of the kept region: detailed texture (foliage, fabric, fur) compresses less efficiently than smooth sky or solid background, so two same-pixel-count crops can produce different file sizes. To force a target size, follow up with Compress AVIF and set a target file size in KB or MB.

Can I crop and convert to JPEG or PNG in one step?

The crop tool outputs AVIF. To crop and switch formats, run this tool first, then Convert AVIF to JPG, Convert AVIF to PNG, or Convert AVIF to WebP on the cropped result. Alternatively, convert first to your target format and then Crop PNG, Crop JPG, or Crop WebP — the order rarely affects the final pixel quality, but starting with AVIF and converting last keeps your intermediate file smaller.
