Precise resize
Use longest edge, exact dimensions, percentage, or fit-inside sizing—with the option to protect smaller images from enlargement.
What it does
One workspace for the changes every image batch needs.
Choose a folder, preview a real image, combine the right operations, and save the whole batch without repeating the same steps file by file.
Format and compression
Move between popular image formats and balance visual quality against file size for sharing, publishing, or archiving.
Consistent framing
Center-crop every selected image to common square, portrait, wide, or photographic aspect ratios.
Batch watermark
Place a consistent text watermark across an entire set with adjustable position, scale, and opacity.
Clean backgrounds
Remove image backgrounds for catalogs, listings, presentations, and creative compositions.
Names and PDFs
Create orderly filename sequences or combine selected images into one convenient PDF document.
How it works
From folder to finished batch in three steps.
1
Bring in your images
Select a complete folder or hand-pick files from different locations.
2
Build the result
Preview and apply the same resize, format, crop, watermark, or adjustment settings.
3
Save with confidence
Create copies in another folder or explicitly choose to replace the originals.
Questions
What to know before your first batch.
Do my images leave my computer?
No. Image processing happens on your device. Background removal may download its processing model, but your selected image content is not uploaded for processing.
Do I need an account?
No account or sign-in is required.
Which image formats are supported?
LumaFlow supports common formats including JPG, PNG, WebP, HEIC, TIFF, BMP, GIF, and AVIF. Availability can depend on the source file and selected output format.
Will LumaFlow overwrite my originals?
Not unless you explicitly choose “Replace original files” when saving. The default workflow saves processed copies to another folder.
Can I process folders with subfolders?
Yes. Folder import scans supported images inside the selected folder and its subfolders.
Can I combine several operations?
Yes. Build a batch from multiple operations, preview the effect, and process the selected images together.
Is LumaFlow a subscription?
Current availability and pricing are shown on the Microsoft Store listing.
Where can I get help?
Email support@iamdev.me with questions, problems, or feedback.
