About invert pdf colors
Flip the colours of any PDF for easier night reading or low-vision accessibility. Text stays selectable. It sits in the pdf & office shelf alongside 83 other pdf & office tools, needs no account, and keeps the same behaviour whether you open it here or call it through the REST API.
It takes a file in PDF and gives back PDF. It is built for files larger than the usual upload ceiling. The work happens on our servers, and the upload is encrypted per file and deleted an hour later — 24 hours if you are signed in. The same operation is available programmatically at POST /v1/pdf/invert.
Invert PDF Colors questions
Are photographs inverted too?
Yes, and they cannot be exempted — the inversion covers the whole page, photographs included. If you need the images left alone, use your reader’s own dark mode instead of converting the file.
Does inverting break text searchability?
No. We invert via a Ghostscript color transfer function, so text stays selectable and searchable.
