An image converter for Windows that does whole folders
Image Converter converts, compresses, resizes, rotates and cleans many photos at once: JPG, PNG, WebP, HEIC, TIFF, GIF, BMP, ICO and more. Presets are named for the job, the new files get names you choose, and everything happens on your PC.

How it works
4 steps, start to finish.
Drop the images
Single files, or a folder to add the images directly inside it.
Pick a tab
Convert, Compress, Resize, Rotate or Clean details.
Pick a preset or set it yourself
For example “Smaller for the web · WebP”, or Email 1600 for resizing.
Run it
New files never overwrite old ones. Resizing, rotating, cleaning and compressing can also replace the originals, which go to the Recycle Bin.
What it can do
Image Converter, in detail.
Convert
Presets “Opens everywhere · JPG”, “Smaller for the web · WebP” and “Keep transparency · PNG”, or any of ten output formats.
Compress
Low, Medium or High, or a quality slider. PNG can drop to 256 colors. A file that would come out bigger isn't saved.
Resize
By percent, longest side or a box to fit, with Web 1920, Email 1600, Thumbnail 320 and Instagram portrait 1080×1350 presets.
Rotate
90° right or left, 180°, or flip horizontally or vertically.
Clean details
Remove GPS location, camera details, dates, comments and editing history. JPG, PNG and WebP are cleaned without re-encoding.
Names you choose
Keep the usual name, add a word, or use a pattern with {name}, {n} and {date}.
HEIC and AVIF are read with Windows' own codecs. For HEIC that's the free HEIF Image Extensions and HEVC Video Extensions from the Microsoft Store; Toolyn tells you if one is missing.
Questions
Image Converter: plain answers.
Is there a limit on how many images?
Dropping a folder adds up to 2,000 images from it. Single files can be added on top.
Can it replace my originals?
For compressing in the same format, resizing, rotating and cleaning details, yes. The originals go to the Recycle Bin; files on USB sticks and network drives are kept.
Does compressing make photos look worse?
At Medium or High most people can't tell. Toolyn never keeps a compressed file that came out bigger than the original.
Are my images uploaded?
No. Every job runs on your PC.
