About this tool
Batch blur workflows
Obscure sensitive content across many screenshots before sharing a folder, soften a whole set of backgrounds for a website, or give a gallery one uniform dreamy softness. Batch blur is the standard prep step before publishing screencasts and tutorials. For one image at a time, the single-image blur tool does the same job.
One setting, every file
One blur radius drives the whole batch: set it once and every image receives the identical blur treatment — the same pipeline the single-image version runs, applied to each file in turn. Nothing is uploaded: the batch is processed on your device, originals are never modified, and you download each finished image individually in its original format.
Frequently asked questions
How many images can the batch handle?
As many as your browser can hold in memory — dozens of typical photos are routine. Very large batches simply take proportionally longer, and every file is processed on your own device.
Is the batch result identical to the single-image blur tool?
Yes — every file runs through the same blur pipeline as the single-image version. One setting drives all of them; nothing is averaged or compromised across the batch.
What blur radius hides text in screenshots?
For typical screenshot text, a radius of 8 or more makes characters unreadable. Check the sharpest, highest-resolution file in your batch at that setting — it is the one that reveals the most.
