What Foliu does.

Extract images
Pull every image from any PDF. Preview, pick, save to Photos or Files.
Merge
Combine multiple PDFs into one. Drag to reorder before merging.
Split
Break a PDF into pieces. Every page, custom ranges, or fixed intervals.
Rotate
Turn selected pages by any angle. Pick individually or rotate all at once.
Reorder
Drag pages into the order you want. See thumbnails, rearrange, done.
Compress
Reduce file size with a visual quality picker. See exactly how much smaller.
Convert
PDF to images, PDF to text, or images to PDF. Three modes, one tool.
Watermark
Add text watermarks with live preview. Position, size, color, opacity.
Sign
Draw your signature, save it, place it anywhere. Your handwriting, your style.
