What it does
Whole folders, in one pass
- Drop up to 500 files, or whole folders, with an option to include subfolders.
- Files convert in parallel with live progress. A file the app can’t read is skipped with a plain-English reason and the rest of the batch carries on.
- Files are saved next to the source by default. A name clash produces
name_2.ext, and nothing is overwritten unless you turn “overwrite” on. Cancelling leaves no partial files. - Format is detected from the file’s content, not its extension, so a
.jpgthat is really a HEIC still opens.
iPhone photos open out of the box
- HEIC decoding is built in (libheif is bundled), so you don’t need Microsoft’s HEIF or HEVC extensions.
- EXIF orientation is always applied, so photos taken in portrait come out upright.
- Metadata is stripped by default: EXIF, GPS location and XMP are removed from the output. Switch “Strip metadata” off if you want to keep it.
One-click presets
iPhone photos → JPG, Web images → PNG, Make icon (ICO), Scan pages → PDF, and Email size (JPG, longest side 2048 px, quality 80). Each preset sets the format and options; you can still change anything afterwards.
Output options
- JPG: quality 1–100 (default 90), with a background colour for transparent images.
- WebP: quality setting, or lossless.
- PNG, BMP: as-is. TIFF: LZW compression.
- ICO: multi-resolution icons from 16 to 256 px in one file.
- PDF: one image per page, page size equal to the image. Or the other way: export PDF pages as images at 150, 300 or 600 DPI, for a page range or the whole document.
- Resize by longest side, width, height or percentage, with Lanczos resampling. It never upscales unless you tick “allow upscaling”.
Offline and yours
The app doesn’t upload your images; conversion happens on your PC. There is no account, no watermark and no daily cap. It is DRM-free and runs without Steam once installed, and it never asks you for a review.
Requirements and platform notes
- Windows 10 or 11, 64-bit. About 150 MB of disk.
- SteamOS and Linux: a native x64 build. Drag and drop works in Desktop Mode. In Game Mode there is no drag and drop, so use the Browse button; it starts in
~/Pictures, and SD cards are under/run/media/. Controller-only use in Game Mode hasn’t been verified by us, so plan on Desktop Mode with a mouse or the trackpads. - No macOS version.
Questions people ask before buying
Can it convert images to HEIC or AVIF?
No. It opens HEIC and AVIF and saves JPG, PNG, WebP, TIFF, BMP, ICO or PDF. If you need HEIC or AVIF output, this isn’t the right tool.
Do I need Microsoft's HEVC or HEIF extension to open iPhone photos?
No. HEIC decoding is built into the app, and rotated photos come out upright.
Does it upload my photos or keep location data?
It doesn’t upload anything. EXIF and GPS metadata are stripped from the output by default; switch “Strip metadata” off to keep them. We tested this with a HEIC carrying GPS coordinates; see the convert without uploading guide.
Will it convert animated GIFs or WebPs, or multi-page TIFFs?
Only the first frame or page. For animated files, Simple GIF Maker accepts GIF input and saves GIF or animated WebP.
Does it work on SteamOS and the Steam Deck?
Yes, it’s a native Linux build. Use Desktop Mode with drag and drop, or the Browse button in Game Mode. Controller-only use hasn’t been verified by us. It has no Steam Deck compatibility rating.
How fast is it?
It depends on your PC and the source files. On this site’s build machine (an 8-core desktop), 12 HEIC photos of about 3,840 × 2,560 px converted to JPG in about a second using the same decoding library the app uses; the bulk conversion guide has the measured table and the method.
