Batch Convert and Compress Images to WebP Without Losing Quality (Free, Offline)

Uploading photos to a website? Converting a whole folder to WEBP and compressing it usually gives the best size-to-quality ratio. APIC handles hundreds of images in one pass, offline.

Supported formats

PNG, JPG, WEBP, BMP, TIFF, ICO and more can be viewed, edited and converted.

Convert and compress a folder

Run APIC.exe and drag your images — or a whole folder — onto the window.
Choose Convert and pick WEBP (or PNG, JPG, BMP, TIFF, ICO).
Add the Compress operation to cut file size without visible quality loss.
Start the batch; progress for all files is shown in one pass.
Check the results — editing and conversion are non-destructive unless you choose to overwrite originals.

No download? Use APIC Web

For a quick job on any device, open APIC Web, which runs in your browser. The portable Windows app remains the full-power option for large batches.

Find images fast

Use Image Search to locate any image on your system by format, size or name before you batch it.
