ImagesConverter

Convert and compress your images, and clean their metadata. Everything runs locally.

Download

Grab the latest installer from the Releases page. These builds are not signed, so your OS will warn you on first launch:

Platform	File	First launch
Windows	*-setup.exe or .msi	SmartScreen warns: click "More info", then "Run anyway"
macOS	.dmg	Right-click the app, then "Open"
Linux	.AppImage (portable), .deb or .rpm	Nothing special, chmod +x the AppImage

Features

• Drop files anywhere in the window, or browse, to convert JPEG, PNG, WEBP, GIF, BMP and TIFF images to JPEG, WEBP or PNG.
• Optional Instant Convert mode: arm the lightning toggle next to the Convert button and images are processed the moment you drop them, no click needed. Off by default, remembered across launches.
• Metadata is always removed: EXIF, GPS coordinates, XMP, IPTC, comments. When the file is already in the target format, the cleaning is lossless, since the app rewrites the container without re-encoding a single pixel.
• The ICC color profile is deliberately kept. It contains no personal information (it is a generic file shipped with your camera or screen), and removing it would visibly shift the colors of wide-gamut images.
• To guarantee a precise weight, give a maximum size in KB: the app searches for the best quality that fits, and only downscales as a last resort. Lossy PNG relies on built-in palette quantization, so there is no external tool to install.
• The EXIF orientation is applied before the metadata is stripped, so rotated phone photos come out upright.
• Optional background removal on your machine: an AI model (ISNet) cuts the subject out and the background becomes transparent, for WEBP and PNG targets. Off by default; the first activation downloads the model and its runtime once (~250 MB, checksum-verified), then it runs fully offline. Images never leave your computer.
• Every file is processed on its own CPU core.
• Existing files are never overwritten (a numbered suffix is added instead), and an original is only deleted once its replacement is fully written.
• Native on Windows, macOS and Linux: a few MB, instant startup. The app never touches the network, with one exception: the explicit background-removal download above.

Verify your download

Each release ships a SHA256SUMS manifest signed with the author's minisign key. The public key is:

RWTz3c4gUmglCX5Uvjthigz1ts3TS3ZSdhRNpFgOJRW/Wr4XjGlqTR3O

Download SHA256SUMS and SHA256SUMS.minisig into the same folder as your installer, then run the two checks for your platform: the signature proves the hash list comes from the author, the hash proves your file was not altered.

Windows (PowerShell)

Get minisign.exe from the official releases (win64 zip, x86_64 folder).

minisign -Vm SHA256SUMS -P RWTz3c4gUmglCX5Uvjthigz1ts3TS3ZSdhRNpFgOJRW/Wr4XjGlqTR3O

$file = "ImagesConverter_2.1.0_x64-setup.exe"   # the file you downloaded
$hash = (Get-FileHash $file).Hash.ToLower()
if (Select-String -Quiet -SimpleMatch "$hash  $file" SHA256SUMS) { "OK: $file matches" } else { "MISMATCH - do not run this file" }

macOS

brew install minisign
minisign -Vm SHA256SUMS -P RWTz3c4gUmglCX5Uvjthigz1ts3TS3ZSdhRNpFgOJRW/Wr4XjGlqTR3O
shasum -a 256 --check SHA256SUMS --ignore-missing

Linux

sudo apt install minisign   # or your distribution's equivalent
minisign -Vm SHA256SUMS -P RWTz3c4gUmglCX5Uvjthigz1ts3TS3ZSdhRNpFgOJRW/Wr4XjGlqTR3O
sha256sum --check SHA256SUMS --ignore-missing
