57 tools, one rule
Nothing is asserted that could be computed. Contrast comes from WCAG 2 and APCA at your real size and weight; QR scannability is graded under the ISO standard for symbols rather than the one for text; a compressor reports the saving it actually achieved, including when a file came out larger.

of your file leave this device. Every tool decodes, edits and re-encodes in the browser tab, which is why none of them can ration you.
83.9%
of the top million home pages fail colour contrast. Last year it was 79.1%. It is getting worse, not better.
WebAIM Million, 2026
A free PDF service will merge twenty-five files but compress two, delete your document after an hour, and ask for an account before you can do it twice — not because the work is hard, but because it is running on a machine somebody rents. The limit is the business model, not the problem.
The design tools fail differently. Every designer already has a contrast checker bookmarked, so detection was never the missing piece. What is missing is the step after the verdict.
“Most want to follow the WCAG rules but get stuck going in circles not knowing how to fix colour contrast issues.”
Both disappear if the work happens on your own device and the tool is willing to show you its arithmetic. That is the whole design brief, and it is why a PDF merger and a contrast checker belong on the same site.
Nothing is asserted that could be measured.
Each of these is a place where the usual free tool gives you a verdict and stops, or gives you a number it did not actually check.
Colour
Holds your hue
The search for a passing colour runs in OKLCH, where lightness is perceptually uniform, and ranks candidates by CIEDE2000 — so the smallest visible change comes first, not merely the first one that passes.
Open the toolBranding
Grades the symbol
A QR code with a logo on it is graded under ISO/IEC 15415, the standard for symbols, rather than being eyeballed. We measured where the ceiling actually is: 4.3% coverage at L, 19.3% at H.
Open the toolFiles
Reports the real saving
A compressor tells you the saving it achieved on your file, including the times it came out larger — which is what happens when you re-encode a PDF that was only ever text.
