PRIVACY & USE
Your images stay on your device.
ShrinkBatch edits selected images, extracts color palettes and creates collage, PDF and ZIP files in your browser. We do not upload those images to an image-processing server.
Last updated: September 6, 2026.
Files and shared links
Your working images, original names, chosen batch name, watermark text, text-image content, Base64 input, color choices and previews stay in the page memory. They are not included in analytics events. The page clears this working state when closed or refreshed. Downloads are saved to the location managed by your browser.
A settings link contains format, target size, maximum width and quality. A result-sharing message also contains the processed file count and combined input and output sizes. Sharing is optional and requires you to copy and send the text yourself. Anyone you send a link to can read its settings.
Encoded images and file reports
Base64 encoding and decoding preserve the original image bytes, including any embedded metadata. A data URL is readable by anyone who has it. Image reports include dimensions, file size and a checksum calculated on your device. These outputs are shared only if you copy or download and send them yourself.
Optional Google Analytics
Analytics is off until you choose Allow analytics. With permission, Google Analytics receives page visits and limited interaction data such as the tool used, file counts, output format, processing time, errors and download or share-button actions. It may also process browser, device, network and approximate-location information. This is not a promise of anonymity. Google signals and advertising personalization are disabled in our Analytics configuration. Your analytics choice is separate from your advertising choices.
We exclude image contents, filenames, entered text, Base64 data and extracted colors. We discard arbitrary query strings and URL fragments from the page URL sent to analytics. Only a fixed set of campaign labels is kept so we can distinguish launch and shared-link visits. Referrers are reduced to their origin.
Your preference is stored in this browser using local storage. If enabled, Google Analytics uses cookies. Use Analytics preferences in the footer to turn it off; future measurement from this page is disabled and this site's Analytics cookies are removed. This does not erase data already received by Google. See Google's privacy policy and Google Analytics data collection information.
Other nnuer.site tools
TimeDrop provides event links, time-zone conversions and date calculators on time.nnuer.site. Its event details and calculations are processed in the browser. Shared links contain a readable event title, time and duration; anyone with a link can read them. See the TimeDrop privacy notice for its data handling and limitations. Advertising on these tools uses the same nnuer.site publisher account and Google consent settings. The consent message identifies this shared publisher as nnuer.site.
TextFold provides browser-based text cleanup, counts, case conversion, list processing and invisible-character inspection on text.nnuer.site. It does not send input to a text-processing API or save it in a database. Copying and downloads are chosen by the visitor. It uses the same Google advertising consent settings. See the TextFold privacy notice for third-party scripts, agent tools and processing limits.
Hosting and advertising
The hosting provider receives normal requests for this website and may keep technical connection or security logs and set cookies for security or bot detection. The local image-processing claim does not mean that visiting any website creates no network requests.
Google AdSense helps fund the free tools. Google and its advertising partners may use cookies, identifiers, your IP address, browser information, page URL and prior visits to this or other websites to deliver, personalize and measure ads. The ads available to you depend on your location, privacy choices and advertising availability. We do not include your image contents, filenames or entered text in our advertising requests.
Where European consent rules apply, Google's consent message lets you accept, decline or manage advertising choices. Use Ad privacy choices in the footer to revisit that decision. In supported US states, Google's Do Not Sell or Share My Personal Information link lets you opt out. These controls are supplied by Google and appear where applicable. Declining optional analytics does not by itself change advertising preferences.

Using the results
Process files you are entitled to use. Check the exported image and the destination's size and format requirements before submitting it. We cannot guarantee that a destination will accept a file or that a particular compression level will preserve all detail. Keep your original files. The tool is provided as available and may change.
Operator and contact
