FAQ
Will content get cut off?+
Default mode preserves aspect (fit), so nothing clips. If pages are larger than the target, they shrink with margins; smaller, and margins are added.
Letter vs A4?+
Letter is US standard (216×279mm); A4 is Korean/EU standard (210×297mm). Letter is slightly wider and shorter.
Will a printed PDF look good after resizing?+
Shrinking is usually clean. Enlarging may lose quality — re-export from the source if possible.
Different size per page?+
Currently all pages get the same size. Use split/convert/merge for per-page sizes.
B5 or A5?+
Common ISO sizes (A and B series) and US Letter/Legal are supported. For unusual sizes, use [PDF Page Crop] or other tools.
