Website Thumbnail Generator

Paste a URL and get a small, light preview image of the website - ready for a directory, a portfolio or a list of links. Pick 320, 480, 640 or 800 px wide, and turn 20 sites into thumbnails in one go from the Batch tab.

How to make a website thumbnail

Paste the URL. Type or paste the address of any public website.
Pick the size and shape. 320, 480, 640 or 800 px wide, in 16:10, 16:9, 4:3 or square - or leave the shape as captured.
Choose the format. JPG is selected - small and accepted everywhere. WebP is smaller still, PNG is the sharpest.
Capture and save. Press Capture and download the thumbnail. For a whole list of sites, use the Batch tab.

The page is captured at full size first and shrunk afterwards, so the thumbnail shows the real desktop layout - just smaller.

Which thumbnail size do you need?

Pick a width, then a shape. With a shape set, every thumbnail comes out at exactly the same size - whatever window or page length it was captured from.

Width	16:10	16:9	4:3	Square	Good for
320 px	320 x 200	320 x 180	320 x 240	320 x 320	Dense lists, tables, bookmarks pages
480 px	480 x 300	480 x 270	480 x 360	480 x 480	Directory cards and link collections
640 px	640 x 400	640 x 360	640 x 480	640 x 640	Portfolio grids, blog round-ups
800 px	800 x 500	800 x 450	800 x 600	800 x 800	Case studies, large cards, retina screens

When the capture is taller than the shape, you choose what stays: the top (header and headline) or the middle. Wider captures are trimmed evenly on both sides.

Need the social card shape? Choose Custom under Device and type 1200 x 630.

Thumbnails for a whole list of sites

Open the Batch tab and paste up to 20 URLs, one per line.

Every site gets the same size and format, each row shows its live progress, and three or more thumbnails download as one ZIP.

Files are named after the site and the size, like example.com-thumb-480x300, so they sort themselves in a folder.

Building a directory? Grab each site icon too with the Favicon Extractor.

Tips for thumbnails that look good

Stay on Desktop

Full HD fits more of the page in, but text turns to dust at 320 px. The 1280 px window keeps headlines readable.

Keep banners hidden

A cookie pop-up fills half a thumbnail. They are cleared by default - leave that on.

Give sliders a moment

Hero images and fonts need time. The 3 second wait suits most sites; slow ones need 5.

WebP for your own site

Hosting the thumbnails yourself? WebP at 85% is the lightest. For email or documents, stay with JPG.

Want to squeeze them further? Try Compress JPG. Need an exact size? The Image Resizer does that.

Safe by design

Our browser visits each page as an anonymous, logged-out visitor.

It only talks to public websites. Every request, including redirects, images and scripts, is checked, and anything pointing at a private or local network is refused.

Captured files are deleted from the server after 4 hours. Your recent captures stay in your own browser.

Frequently Asked Questions

Paste the URL above, pick a width and press Capture. We open the site in a real browser, take a screenshot of the first screen and shrink it to the size you chose.

320, 480, 640 or 800 pixels wide, in 16:10, 16:9, 4:3 or square. At 480 px that is 480 x 300, 480 x 270, 480 x 360 or 480 x 480.

Choose Full size to keep the capture as it is, or As captured to keep the shape of the browser window.

Open Thumbnail width and pick a shape: 16:10, 16:9, 4:3 or Square. Each capture is cropped to that shape before it is shrunk, so a grid of thumbnails lines up perfectly.

Choose whether the top or the middle of taller captures is kept.

JPG is the safe default: small files that open everywhere. WebP is smaller at the same quality and fine for modern websites. PNG is the sharpest and the heaviest.

Yes. The Batch tab takes up to 20 URLs per run and returns one ZIP. There is a fair-use limit of 10 captures a minute and 120 an hour.

No - download it and host it yourself. Captured files are deleted from our server after 4 hours, so a direct link would stop working.
