About this tool
Batch sharpen workflows
Crisp up a whole folder of slightly soft shots, restore bite to a set of downscaled thumbnails, or give every product image in a catalog the same finishing pass. Batch sharpening as the last step makes an entire set feel professionally finished. For one image at a time, the single-image sharpen tool does the same job.
One setting, every file
One sharpening amount drives the whole batch: set it once and every image receives the identical sharpen 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 sharpen tool?
Yes — every file runs through the same sharpen pipeline as the single-image version. One setting drives all of them; nothing is averaged or compromised across the batch.
Should already-sharp photos skip the batch?
If some files are already crisp, they will show halos first. Sort the obviously sharp ones out, sharpen the soft majority, and give the crisp few a pass at half the amount — or none at all.
