See all →Animated WebP extract frames
Extract every frame of an animated WebP as PNGs.
Blockhash (perceptual)
Compute a perceptual block-hash of an image (similar images produce similar hashes).
Count shapes
Count distinct objects in an image.
Dedupe check
Check whether two images are duplicates / near-duplicates.
Detect ArUco markers
Detect ArUco fiducial markers in an image.
Detect blur (quality check)
Score an image's sharpness / blurriness.
Detect circles
Detect circles in an image (Hough transform).
Detect contours
Find object outlines (contours) in an image.
Detect lines
Detect straight lines in an image (Hough transform).
Find template
Find a smaller template image inside a larger image (template matching).
GIF extract frames
Extract every frame of an animated GIF as PNGs.
Image detect barcode
Detect and decode 1D barcodes (EAN, UPC, Code 128, etc.).
Image detect document
Find a paper document in a photo and rectify its perspective.
Image detect QR
Detect and decode QR codes in an image — including rotated, perspective-warped, or partially occluded codes.

Pixel-level diff between two PNGs. Returns the diff image plus a similarity score.
Image dominant colors
Extract the most prominent colours from an image.
Image EXIF
Read EXIF, IPTC, and XMP metadata from a JPEG.
Image face detect

Image histogram
Compute per-channel pixel-value histograms (R/G/B/luminance) for an image.
Image info
Read an image's dimensions, format, and other basic metadata.
Image perceptual hash
Compute a perceptual hash (DCT-based pHash) of an image.
Match features (ORB)
Find matching feature points between two images (ORB / SIFT-style matching).
QR decode
Decode a clean, head-on QR code from an image.
QR encode
Generate a QR code from text or a URL.
