About this tool
Everything here happens in your browser, so the file you load is the only copy that exists. Invert PDF colors into comfortable OLED dark mode, classic negative inversion or warm sepia paper tint for night reading and toner-saving printing. Private by design. Processing runs locally in your browser's memory — the document is never transmitted, and closing the tab clears it completely. The workflow is deliberately short: load the file, choose the options on the page, run the operation, and save the result. Every choice is applied before the file is written, so re-running with different settings takes seconds. Practical limits apply (see the on-page limits); it pairs well with the related tools linked beside this page when one step is not the whole job. Key facts — Processing: runs entirely in your browser, client-side; Access: free with no account required; File limits: see the on-page limits; Privacy: the file never leaves the device.

FAQ
Does dark mode degrade text sharpness or blur resolution?
Not at all. The transform applies native PDF vector blend modes, retaining all original vector fonts and vector geometry with infinite sharpness.
What are the benefits for printing?
Presentations with dark backgrounds waste excessive toner. Inverting converts dark backgrounds to white, saving up to 80% of ink and toner costs.
Does inverting colors preserve selectable text and hyperlinks?
Fully preserved. Vector blend modes change only rendering colors. The underlying text layer, clickable hyperlinks, and bookmarks stay fully intact.
Which color modes are available?
Three presets: OLED dark mode (comfortable night reading), classic negative inversion (turns dark slides white for toner-saving printing), and a warm sepia tint (relaxed long-session reading); for grayscale output, pair the result with our Grayscale PDF tool.
How long does it take to invert a long lecture deck?
Very fast. Injecting blend mode instructions into page streams avoids rasterization re-encoding, processing hundreds of pages in seconds.
