Frequently asked questions

What is Add watermark?

Add a text watermark to an image.

When would I actually use this?

Preparing an image for somewhere specific: cropping to an aspect ratio, resizing under an upload limit, straightening a photo, or shrinking a file that is too heavy.

What is the most common mistake?

Enlarging a small image and expecting detail. Upscaling invents pixels from the ones already there; it can smooth an image but it cannot add information that was never captured.

How is Add watermark different from Add a border to an image?

They sit next to each other but answer different questions: Add a border to an image is the one to open when you need it to frame a picture with a solid border of the width and colour you pick. Pick whichever matches what you're starting from — both are free.

Is there a tool for the next step?

Add Line to Image is the closest one after this: Draw freehand lines on an image — pick color, width and style, undo, and download — all in your browser.

What else is worth having open alongside it?

Add margins to an image and Add Text to Image — they come up in the same task often enough to be worth a second tab.

Where do the figures come from?

Editing goes through the browser's canvas, and the output carries no watermark. Re-saving a JPEG re-compresses it, so work from the original rather than from an already-edited copy.

ExplainerWatermarking: What It Protects, and What It Does NotA visible mark lives in the pixels, so it survives every copy — and degrades the image for every honest viewer at the same time. Measured: what a corner mark costs, what a tiled mark costs, and how each compares to metadata credit, Content Credentials and invisible watermarking.GuideHiding a Face, a Plate or an IBAN in an Image — PermanentlyBlur and pixelation are reversible — not by undoing the maths, but by guessing forwards. Against this tool's own blur and pixelate modes, a recovery attack returned the hidden value at rank 1 of 10,000. Both modes have since been removed. Here is what is left, and why it cannot be attacked the same way.How-toSending a Document for Signature: the Workflow, Not the LawWhether a drawn signature is valid is settled elsewhere. What decides whether your document actually gets signed is the order you ask people in, what the audit trail records, and six failure modes that have nothing to do with the law.ExplainerA Drawn Signature Is a Real Signature — Just Not a Qualified OneDrawing your name onto a PDF produces a simple electronic signature. European law says that cannot be dismissed just for being electronic — and also that it carries none of the presumptions a qualified signature does. Knowing which tier you have is the difference between a document that holds and one you have to defend.How-toHow to Compress an Image Without Losing QualitySmaller images load faster and rank better.

The twenty-file lists are a dead browser matrix — with measurements showing what a 16-pixel icon can and cannot hold.
