🔒 This tool runs entirely in your browser — your files are never uploaded to any server.

Image Placeholder Generator creates blank filler images you can drop straight into a design, prototype, or code project. Set the exact dimensions, pick your background and text colors, add an optional label, choose a file format, and download — the whole process takes a few seconds and happens entirely in your browser.

Tool interface

Adjust the settings and click Generate to produce the image, then Download to save it:

  • Width / Height — enter any pixel dimensions from 1 to 9999. Eight common presets (1920×1080, 1280×720, 800×600, 600×400, 400×400, 300×250, 728×90, 160×600) are available as quick-select buttons
  • Background Color — choose or type a hex color; defaults to #cccccc
  • Text Color — color of the dimension label and diagonal lines; defaults to #7a7a7a
  • Custom Text — override the default width×height label with any text (e.g. "Hero Image", "Avatar")
  • Format — PNG (lossless), JPEG (with quality control), WebP (with quality control), or SVG (vector, infinitely scalable)
  • Quality — available for JPEG and WebP; choose 70 %, 80 %, 90 %, or 100 %

The preview panel updates live as you change settings and shows the image scaled to fit, with a checkerboard background to indicate transparency.

Common use cases

  • UI prototyping — fill in image slots in Figma exports or HTML mockups with correctly sized placeholders
  • Web development — use during development before production assets are ready, without relying on third-party placeholder services
  • Presentations — quickly create slide image blocks at the exact dimensions required
  • Email templates — generate correctly sized filler images for each content block while copy is being finalized
  • Documentation — illustrate layouts in technical docs without sourcing real photos
  • Banner ads — produce blank canvases at standard IAB ad sizes (728×90, 300×250, 160×600, etc.)

FAQ

What does the generated image look like?

Each image has a solid background, a diagonal cross (X) drawn at low opacity, a border, and a centered label showing the dimensions or your custom text. This is the universally recognised placeholder pattern.

Which format should I use?

Use PNG for most purposes — it is lossless and universally supported. Use SVG when you need a vector image that scales without quality loss at any size. Use JPEG or WebP when file size matters and a small amount of compression artefacts is acceptable.

Can I use a transparent background?

The current tool uses solid background colors. For a fully transparent PNG, set the background color to match your page background, or open the downloaded PNG in an image editor and remove the background.

Is there a size limit?

The browser canvas API can handle large dimensions, but very large images (e.g. 8000×8000 px) may be slow to render or may fail on low-memory devices. For most practical purposes up to about 4000×4000 px the tool works without issue.

Is anything uploaded or stored?

No. All drawing is done locally with the HTML5 Canvas API. Nothing is uploaded, and no image data is stored anywhere.

Can I use the downloaded images in commercial projects?

Yes. The images are generated by your browser from your own inputs and contain no third-party content. You own whatever you generate.
