Check encoded and display dimensions
Read JPEG, PNG or WebP width and height without decoding the pixels. Valid EXIF orientation changes display width and height where needed. Missing, invalid and unsupported values stay distinct.
Supported files and output
Read encoded and EXIF-orientation-aware display dimensions, exact pixel count and aspect ratio without decoding JPEG/PNG/WebP pixels, up to 20 MiB. Set positive whole-number maximum width, height and byte limits; unreadable dimensions remain unknown. Missing EXIF uses encoded orientation with a warning, while invalid or conflicting EXIF does not produce a guessed display size. Animation canvas and first-JPEG dimensions carry explicit limits.
Read the result with its coverage
Stored fields can be edited, copied or removed. A successful read describes the selected file’s supported containers; missing fields cannot be recovered from its pixels. A damaged or unsupported container has its own result. Review private values before copying or sharing a report.
These file operations run locally. The separate image checker can send file-header data and a reduced image copy for a model reading. Read the method and limitations when that is the task you need.
Continue the task
- Image file checks: format, dimensions, hashes and defined pixel differences — Choose a local file check for container type, display dimensions, exact duplicate bytes or native-size sRGB RGBA differences, with three reproducible synthetic scenes.
- Prepare an image file for the check you need — Check actual format, byte size, encoded/display dimensions and known file history, then choose a supported local field, hash, pixel or optional model workflow.
- EXIF viewer and exports — Inspect the stored camera, location and caption fields.
- Remove selected metadata — Create a verified static-image copy with supported categories removed.
- Choose another file operation — Browse available tools by task.
