Three ways to start
Pick whatever fits the moment.
Click the icon
The side panel opens next to your page. Drop files in, pick a format and download them one by one or as a ZIP.
Right-click
“Shrink this image” on any image on the web, and “Shrink this PDF” on links to a PDF.
Scan a page
See at once which images on a page are too heavy and how much you can save.
What’s inside
Resize
By width, height, percentage, to fit in a box or to an exact size, with smart cropping. Never enlarged.
Convert
To JPG, PNG, WEBP or AVIF, or keep the original format.
Compress
Quality 1 to 100, or a maximum file size in KB: the extension finds the highest quality that fits.
PDFs
Small, medium or high, in greyscale, or every page as JPG or PNG.
Profiles
The same profiles as on verklein.nu: make one on the site and it is in the extension, and the other way round.
Private
Metadata such as GPS is removed by default. Your files are never stored.
Spotlight
How heavy is this page?
Click “Scan this page” and the extension lists every image on the open tab: file type and size, how big it is versus how big it is shown, missing dimensions and lazy loading. With an estimate of what you can save.
- See which JPGs and PNGs could be WebP or AVIF
- Find images that are much bigger than on screen
- Send them to the processing list in one click
On a WordPress site the extension points you to the WordPress plugin, which converts the whole media library in one go.
Extension or website?
The extension keeps it simple on purpose. For more control, there is the website.

Which permissions, and why
Side panel (sidePanel)
To show the extension next to your page when you click the icon.
Context menu (contextMenus)
For “Shrink this image” and “Shrink this PDF” in the right-click menu.
Active tab (activeTab) and scripts (scripting)
Only when you click “Scan this page”: the extension then looks once at which images are on the open tab. It changes nothing on the page and sends nothing on.
Storage (storage)
To remember your settings, only in your own browser.
Access to verklein.nu
Your files are processed on the verklein.nu server, exactly like on the website. On verklein.nu itself the extension also shares your profiles with the site, so you have them in both places.
Access to a website (optional)
Only when you right-click an image the extension cannot fetch otherwise, Chrome asks whether verklein.nu may read that one website. A scan can ask the same, to read the file size of images on another server. You can refuse, and withdraw it later at chrome://extensions.
Frequently asked questions
Is the extension free?
Yes. No account, no subscription and no watermark.
Does it work in Edge, Brave or Opera?
Yes, in every Chromium browser from version 116 that can install extensions from the Chrome Web Store, such as Edge, Brave, Opera and Vivaldi.
Are my files stored?
No. They are processed in memory on our own server, exactly like on the website, and thrown away right after.
Does the extension work offline?
No. Resizing and converting happen on the verklein.nu server, so you need an internet connection.
Why does the extension sometimes ask for access to a website?
Only when you right-click an image that cannot be fetched otherwise, or when a scan reads images on another server. You can refuse, and withdraw it later at chrome://extensions.
How do I remove the extension?
Right-click the verklein.nu icon in your toolbar and choose Remove from Chrome. Your settings are removed too.
Try it in your own browser
Free, no account. It takes a few seconds.
