What image formats can I open and save?

You can open PNG, JPG, WebP, GIF, BMP and most other formats your browser can display. You can save as PNG, JPG, WebP, SVG with editable vector annotations, or a PDF document.

Can I annotate several images at once?

Yes. Drop up to 30 images, or use Add images in the filmstrip. Each image keeps its own annotations, Apply to all copies the current ones onto every image, and Download saves the whole set - more than two images come as one ZIP, or as a multi-page PDF.

Is there a size limit for images?

The limit is your device memory. Desktop browsers handle up to about 40 megapixels and phones about 16 megapixels; larger pictures are scaled down automatically so the editor stays fast.

How to annotate an image online

Add your image. Drop a screenshot or photo into the box, paste it with Ctrl+V, or browse for it. Drop several to annotate a whole batch.
Pick a preset or a tool. Start from Bug report, Tutorial, Redaction, Feedback or Approval, or choose arrows, shapes, text, step badges, blur, spotlight or the magnifier.
Draw and adjust. Drag on the image to draw. Use the Select tool to move, resize, recolour or delete anything you added.
Download or copy. Save as PNG, JPG, WebP, SVG or PDF, copy straight to the clipboard, or download a whole batch as one ZIP.

Press ? in the editor for every shortcut. Need a different format afterwards? Use PNG to JPG or PNG to WebP.

Annotation tools

Every mark stays editable until you download.

Start from a quick preset - Bug report, Tutorial, Redaction, Feedback or Approval - and the right tool, colour and size are picked for you.

Arrows

Straight, curved or elbow, with open, filled or double heads. Hold Shift for perfect 45° angles.

Shapes

Rectangles and ellipses - outline, solid or see-through, solid, dashed or dotted, with an optional drop shadow.

Text & callouts

Plain, outlined or label-style text that stays readable on busy screenshots, plus speech-bubble callouts that wrap.

Step badges

Numbered markers for tutorials. Delete one and the rest renumber; Renumber sorts them in reading order.

Magnifier

Drag over a tiny detail and a zoomed lens appears beside it, joined by a line - ideal for small buttons and fine print.

Spotlight

Dims everything except the area that matters. Several spotlights share one dim layer, so each stays bright.

Pen, marker & highlighter

Smooth freehand strokes with mouse, touch or stylus. The straight edge turns any stroke into a clean line.

Stamps & notes

Crisp vector stamps - check, cross, star, warning, bug, idea - and numbered sticky notes for design feedback.

Want text in a fancy font or a logo on top? The Watermark Image Maker handles branding, and the Meme Generator does bold captions.

Hide sensitive information safely

Screenshots leak more than you think: emails, order numbers, faces, API keys.

Use Pixelate for text and numbers - large blocks can’t be read back. Blur looks softer and suits faces and backgrounds.

Permanent on export. The saved PNG, JPG, WebP, PDF and even SVG contain the replaced pixels, not a removable layer.
Go strong. Push the intensity up for small text - light blur on large letters can stay readable.
Share the image, not the project. A saved project file keeps the original picture so you can keep editing.

Need to blur a whole photo or many faces? Try Censor Photo.

Who uses an image annotator?

Developers

Hit Bug report and draw red arrows straight away. Mark up a folder of screenshots in one sitting and grab them as a ZIP. Capture screens with Screen Capture.

Designers

Pin numbered sticky notes on mockups and magnify the pixel that bugs you. Resize mockups with the Image Resizer.

Educators

Build step-by-step guides with badges that renumber themselves. Sharpen blurry diagrams first with the Image Upscaler.

Support teams

Spotlight the button customers miss, then copy the image straight into the reply. Bundle several shots into one file with Screenshot to PDF.
