How to use the Image Pixelator
Upload your images by dragging one or several files onto the marked area, or click to select them from your device. The tool accepts JPG, PNG, WebP and static GIF and loads every file at once: each image gets a tab with its name above the preview, and the × button next to it removes that image from the list without starting over. The Add images button lets you include new files at any time, and repeated files (same name and same size) are discarded automatically. All processing happens in your own browser — no file is sent to external servers, guaranteeing full privacy.
The image sits on the left and follows the page as you scroll, while the controls stay in the right-hand column. In Whole image mode, just drag the Intensity control: it starts at 0, with the original photo, and the blocks appear in the preview in real time as you raise the value up to 40 pixels. There is no button to confirm — what you see on screen is exactly what gets downloaded, and sliding back to 0 undoes the effect. With two or more images loaded, the same value applies to the whole batch.
Select area mode pixelates only one region: click and drag over the image (or swipe with your finger on mobile) to draw a rectangle over faces, license plates, document fields or any sensitive data, set the selection intensity and confirm with Pixelate Selection. A dashed green border shows the marked region before you apply. You can repeat it as many times as you like, censoring one region at a time, and the Undo button reverts exactly one step per click. Because the selection depends on a manual marking, this mode is only available with a single image loaded.
The intensity sets the block size: smaller values produce a subtler effect, suited to stylistic censoring; larger values create big, clearly visible pixels, recommended when the information must become unrecoverable. Once you are happy with the result, pick the output format — PNG (lossless), JPG (smaller file) or WebP (best balance) — and click Download to save the image on screen. With two or more images, Download all (.zip) packs the entire batch into a single compressed file, keeping the original names followed by "pixelated". Reset brings the files back to their original state and resets the intensity control; Clear all empties the list and returns to the initial screen.
