FileDoodler lets you freely scribble, annotate, and mark up image files and PDFs right from your phone or computer using your finger or mouse, then save a copy. No accounts to create, just easy doodling.
Works in your browser · Saves to your camera roll
What you can do
Load any image from your camera roll and draw directly on top — circle things, add arrows, highlight what matters.
Open any PDF and scribble on every page. Your annotations are saved per page and exported back as a PDF.
Pick from a curated palette or choose any colour. Adjust brush size and opacity for fine details or bold strokes.
Made a mistake? Tap undo up to 30 times. Or erase precisely with the eraser tool.
One tap saves your finished drawing — as a JPG for images, or a full PDF with all your annotations intact.
Add FileDoodler to your home screen for a native app feel. Works offline once installed — no internet needed.
How it works
Tap "Load Image" or "Load PDF" and pick any file from your device. It opens instantly on the canvas.
Pick a colour, adjust the brush, and start drawing. It feels natural and responds instantly to touch.
Hit Save and your annotated file downloads straight to your device, ready to share.
Ready?
No sign-up. No downloads. Just open and draw.
