FREE & PRO

PRIVACY FIRST
Every conversion happens entirely on your device. We never collect data, track usage, or upload your files anywhere. What stays on your device is yours alone.
- New: Create comic book archives (CBZ) — stitch several images into one CBZ in reading order, or convert a PDF to a CBZ with one image per page.
- New: Compress without changing format — shrink a JPEG, HEIC, WebP, or AVIF by lowering the quality or resizing; the file keeps its original type.
- Improved: Office and document conversions (PPTX, ODP, CSV, Pages, Keynote, Numbers) now run off the main thread, so the app stays responsive while they convert.
- Improved: More faithful DOCX tables, including nested tables, plus a range of stability and reliability fixes.
