Lemon for Windows 10 (2004 or later) and 11, 64-bit.

What's new in 0.6.0

  • A tidier Presets page. A strip on the left picks Images, Resize, Audio, Video or Documents, and only that category is listed, with your own presets pinned on top. Each preset says what it does ("WebP · quality 80 · up to 1920 px"). The strip can collapse to icons.
  • Remove background and Upscale in the right-click menu. Remove background, Upscale 2× and Upscale 4× appear for files they work on, once a model is downloaded. Lines now split the menu into groups.
  • The wheel key can be Ctrl, or one side of the keyboard. With Shift, Ctrl or Alt as the key, a Side list picks Either, Left or Right; the other side keeps working as usual.
  • Setup spots what you already have. On the Optional downloads page, converters Lemon can already find are greyed out and marked "installed".
  • Faster to start. Right-clicking several files hands each one to Lemon about 25% faster, and starting Lemon uses about 20% less processor time. The downloads and the installed app are bigger for it: about 50 MB more once installed, about 4 MB more memory.
  • Fixes:
    • A file named like frame%03d.png could be saved over a different file (frame000.jpg), and the conversion then failed. If you've converted files with % in their names, check the folder they were in.
    • To PNG in the right-click menu no longer cuts out the background because you used Remove background last. Optimize likewise can't turn into a Resize or an Upscale.
    • A settings or presets file that can't be read is now kept as a .bad copy instead of being replaced by defaults.
    • Canceling cleans up partial files, and always shows as Canceled.
    • The wheel no longer fails to open for a selection when Explorer returns an empty entry.
    • A GIF from a video respects a max height, so tall videos fit.
    • Remove background reads CMYK pictures correctly.
    • Looking through a big dropped folder no longer holds up the window.
    • Quitting from the tray during a conversion asks first, even if the window was never opened.
    • A closed and reopened wheel can't pick up the files of the wheel before.

Install guide

Installer

  1. Download Lemon-0.6.0-Setup.exe and run it. Or use winget: winget install Kataruna.Lemon (once 0.6.0 is listed there).
  2. If Windows says "Windows protected your PC", click More info › Run anyway (Lemon isn't code-signed yet; Windows only asks once).
  3. Pick your options: the right-click menu, starting when you sign in, and on the Optional downloads page any converters and AI models you want.
  4. Finish, and Lemon starts. It installs to %LOCALAPPDATA%\Programs\Lemon. Setup quits a running Lemon for you (it asks first).

Portable

  1. Download Lemon-0.6.0-Portable.exe and put it where you like (e.g. Documents\Apps).
  2. Double-click it (same SmartScreen note as above). The first launch takes a few seconds while it unpacks to %TEMP%\.net\Lemon; later launches are instant.
  3. Optional, in Settings (gear, top right): the right-click menu, start with Windows, and AI models. These point at the file where it is now: if you move or rename it, switch them off and on again.

First steps

  • Batch: drop files or folders on the window (or Add files), pick a preset per file or Set all to, click Convert. Results are saved next to the originals (or a folder you choose in Settings › Output).
  • Conversion wheel: while Lemon runs (minimized or in the tray is fine), drag files anywhere and shake the mouse or press Alt. Drop on a format to convert right away, or on the lemon to queue. Or select files in File Explorer and hold Alt (see above). Switch rings with the chips under the wheel, Tab, the number keys or the scroll wheel.
  • Wheel tab: look (themes, blur, opacity, center emoji), your own rings and commands, the Convert ring per file kind, and where the wheel opens, with a live preview.
  • Closing the window keeps Lemon in the notification area so the wheel keeps working; right-click the lemon by the clock to quit.

Optional tools

Images (PNG, JPEG, WebP, AVIF, GIF, TIFF, BMP, ICO, HEIC input, PDF output) work out of the box. For more, install these free tools (Setup's Optional downloads page can do the first three); Lemon names the missing one when you add a file it can't convert, and finds tools without a restart.

For Install (PowerShell)
Audio and video, Optimize for videos winget install Gyan.FFmpeg
Documents (DOCX, ODT, RTF, HTML, Markdown, EPUB) winget install JohnMacFarlane.Pandoc
Office files to PDF winget install TheDocumentFoundation.LibreOffice
Optimize for PDFs Ghostscript, from ghostscript.com

Updating and uninstalling

  • Update: run a newer Setup over this one (it quits Lemon for you), or replace the portable file. Settings, presets and models are kept.
  • Uninstall: Settings › Apps › Installed apps › Lemon › Uninstall (also removes the right-click menu and start with Windows). Portable: switch those two off in Lemon's Settings, quit, delete the file.
  • Settings, presets and models stay in %LOCALAPPDATA%\Lemon; delete that folder to remove them too.

If something's off

  • No wheel: make sure Lemon is running (lemon by the clock) and that shaking or a key is on in Wheel › Opening the wheel. Drag actual files (or, with a command for links, a link).
  • No Cut out ring, or no Upscale on the Resize ring: download a model in Settings › AI models.
  • A conversion failed: the error is on the file's row; details are in %LOCALAPPDATA%\Lemon\errors.log. Please attach it to an issue.
