Release Notes
Version 1.0.2 — current release
- AVIF and HEIC input — drop iPhone photos, AVIF assets, or any common image format and convert to AVIF / WebP / PNG / JPG
- Multi-size export — emit every responsive-image variant from a single source in one parallel pass
- Watch folder — point ImageSmasher at a folder; new images auto-convert as they land
- CLI binary — imagesmasher-cli for scripting and CI integration
- Macros — save your “format + quality + size + output dir” recipes and run them with one click
- Right-click integration — “Convert with ImageSmasher” in Windows Explorer (per-user, no admin)
- Auto-update — checks for new versions on launch; manual “Check Now” in Settings
- Keyboard shortcuts, accessibility improvements, decoded-image cache, stream decoding for large files
- Security hardening: stronger machine fingerprint (v2), DPAPI-encrypted license storage, server-side rate limiting, RSA signing keys moved server-side
⚠️ Existing 1.0.0 / 1.0.1 users: the new fingerprint algorithm invalidates previously-issued offline tokens. Open the Pro license window and re-enter your key — your activation count is not affected.
Version 1.0.1 — previous release
- Fixed WebP exports producing 3-4 MB files when they should be 200-400 KB
- WebP quality slider is now honored; previous builds silently forced lossless encoding
- PNG exports now strip the alpha channel for fully opaque images
Previous release history available on request.
Installer Verification
ImageSmasher 1.0.2 installers are code-signed by LXB Studio LLC, a registered Pennsylvania company, with an RFC-3161 trusted timestamp. Right-click the installer in Windows Explorer → Properties → Digital Signatures to confirm the signature is valid and the publisher is LXBSTUDIO LLC.
About the SmartScreen prompt: Windows SmartScreen builds reputation per-publisher over time. Until our certificate accumulates enough installs to be auto-trusted, you may still see “Windows protected your PC” on first run. The signature itself is valid — SmartScreen is simply unfamiliar with our publisher fingerprint. Click More info, then Run anyway to proceed.
🔒 For an additional integrity check, you can also verify either installer’s SHA-256 hash matches the values below.
ImageSmasher_1.0.2_x64-setup.exe
9bd46aac545db6d1365fa6ea80825e30fa0fbfc709099db23ea4bd48bb345c9a
ImageSmasher_1.0.2_x64_en-US.msi
d2a4bd2bc3a734c582493e1eeead64f85cc1b968612612845f27c70632530d6e
How to verify on Windows: open PowerShell in the folder where you downloaded the installer and run Get-FileHash ImageSmasher_1.0.2_x64-setup.exe (or the .msi equivalent). The output should match the value above exactly.
