Output format

Enable only what you need. By default, files convert to the selected format, keep their size, and non-image extras are dropped from archives.

Convert format Writes every image in the format you picked. Turn it off to keep the original format while you resize or rename. Resize Unlocks the size controls below. Leave it off and dimensions stay exactly as they are. Clean file names Strips noise from names: extra symbols, repeated words, and trailing sizes. photo-beach-beach_800x600.jpg becomes Photo Beach.jpg. Flatten folders Puts every image in one folder inside the ZIP. Off keeps the original folder tree. Skip non-images Only images go into the new archive. Documents and other files are left out. Count divisible by 4 Drops a few random extras so the total divides by four — handy for 2×2 grids. Skip this if you need every file.
