Fine tune
Every page is named in order and delivered together in one ZIP file.
Content is fitted proportionally and centered. Extra space becomes blank margins on the sides or top and bottom.
The widest page becomes the target. Narrower pages are resized proportionally until their widths match it, so their heights change naturally and nothing is stretched or cropped.
Embedded fonts, selectable text, editable objects, forms, links, annotations, attachments, scripts, and document metadata.
The visible page appearance, page proportions, and selected raster resolution. Pages are stored as lossless images and normalized to one common width.
Important: text will no longer be selectable or searchable after flattening. Higher DPI produces a sharper but larger PDF.

No areas added yet.
Every rectangle is invisible in the downloaded PDF. Add up to 100 areas across any pages; clicking or tapping one opens its URL.
LZWLossless. Best for text, forms, diagrams, line art and mostly white pages.
DeflateLossless. A good general alternative that can beat LZW on some documents.
JPEGLossy. Usually much smaller for photos, scans, gradients and detailed imagery.
Why can TIFF be large? TIFF stores rendered pixels instead of the PDF’s compact text and vector instructions. Compression, grayscale and lower DPI can reduce the result considerably.
