Compare two images side by side — dimensions, sizes and a byte-identical check, in your browser.
Shows two images side by side with dimensions, sizes, aspect ratios and a byte-identical SHA-256 check.
Load one image per picker, or two in the first picker; Process enables when two are present.
Side-by-side comparison only — not a per-pixel visual diff.
Images are read on this page; nothing is uploaded and originals are not modified.
Compare Images Online places two images next to each other and reports each one's dimensions, file size, MIME type, aspect ratio and a SHA-256 of the raw bytes, so you can see at a glance how they differ. It is a side-by-side comparison, not a pixel-level visual diff.
Upload one image in each picker, or select two images in the first picker. The tool tells you whether the two files have the same dimensions and whether they are byte-identical, and reports the difference in total pixel count.
The two images are decoded only to read their size; the original files are never modified or uploaded, and the downloadable report is a plain-text summary.
One picker for each image, both with drag-and-drop and keyboard support, so the workflow is unambiguous.
A SHA-256 of each file tells you whether the two are exactly the same bytes, not just visually similar.
Labelled as a side-by-side comparison — no hidden, unreliable visual-diff claims.
Both images are read on this page; nothing is uploaded and the originals are untouched.
See how an edited or exported copy compares in dimensions and file size.
Confirm whether two files are byte-identical with the SHA-256 check.
Compare two assets' aspect ratios and pixel counts side by side.
Produce a quick text report when sending images to a client or teammate.
Not in this version. It shows the two images side by side with their dimensions, sizes, aspect ratios and a byte-identical check. It does not yet compute a per-pixel diff, SSIM or PSNR overlay.
Use both pickers — one image on the left and one on the right — or select two images together in the left picker. Process stays disabled until two images are loaded.
Yes. It computes a SHA-256 of each file's raw bytes and reports whether they are byte-identical, as well as whether they share the same pixel dimensions.
No. Both images are decoded by browser APIs on this page only to read their size; no file is sent to a server, and the originals are not modified.
A plain-text report listing each image's name, dimensions, aspect ratio, file size, MIME type and SHA-256, plus the same-dimensions and byte-identical results.
