KhartTool 0.1.0

Drop a file. The wheel already knows.

Convert, shrink and clean any file — just drag it.

KhartTool is a small, free Windows app that sits on your desktop. Drag a photo, video, song or document onto it, hold Shift and pick the format you want — the new file appears right next to the original. Nothing is uploaded, and there is no account to create.

Try it: pick a file type, then hover the wheel. Bigger slices are the formats people pick most.

See it work

Three ways to use it: hold Shift to change a format, hold Ctrl for tools like ZIP or compress, or pick a preset and drop a whole folder. Press a button to watch.

Press Play. A file is grabbed, the modifier lights, and the wheel blooms on the cursor.

Use cases

The small file chores you do every week — now one drag.

No website to find, no upload bar, no "sign up to download". Drag the file onto KhartTool, hold ⇧ Shift to change the format or Ctrl for tools, and the new file appears right next to the original.

Share photos without sharing where you live

The annoyance

Every phone photo quietly stores the exact spot it was taken, plus your phone model and the time. Post a picture of your new couch on a marketplace and you may have just posted your home address.

The fix

Drag the photos (or the whole folder) onto KhartTool, hold Ctrl, release on Metadata. Or pick the Privacy Cleaner preset once and every drop is cleaned.

What you get

Clean copies that look identical but carry no location or camera details — made on your PC, never uploaded anywhere.

When the email bounces: "attachment too large"

The annoyance

You scanned a contract with your phone. Now it's eight photos, 40 MB, and the only "free" fix is a website that wants you to upload a signed contract to a stranger's server.

The fix

Drop the photos → Ctrl → Images to PDF. Then drop the PDF → Compress PDF.

What you get

One tidy PDF small enough to send — and the document never left your desk.

Your shop is slow because the photos are huge

The annoyance

The supplier sent 15 MB product shots. Pages crawl on phones, and shrinking 200 images one by one is an afternoon you don't have.

The fix

Choose the Web Optimizer preset and drop the whole folder. It resizes, strips hidden data and saves web-ready WebP.

What you get

The whole catalogue in one drop (up to 5,000 files) instead of 200 trips through an online resizer.

Grab the audio, make a GIF, cut the boring bit

The annoyance

You want the sound from a voice memo video, or a short GIF for a chat. Video editors take ages to open; online converters add a watermark.

The fix

Drop the clip → ⇧ Shift → Extract MP3 or GIF. Need to trim, mute or speed it up? Ctrl has those.

What you get

The clip you wanted, no watermark, without opening a single editor.

Hide the name in the screenshot before you post it

The annoyance

A screenshot for a bug report or a group chat shows an email, an order number or a face. Opening Paint to scribble over it looks messy and takes too long.

The fix

Drop the screenshot → Ctrl → Blur, Redact or Crop.

What you get

Share it with confidence — in seconds, not a trip through an image editor.

"Can you send it as a PDF?" — done before they finish asking

The annoyance

The school portal only takes PDF. The client sent a spreadsheet as CSV but the tool needs JSON. Your notes are in Markdown and your teacher wants Word.

The fix

Drop the file → ⇧ Shift → pick PDF, DOCX, TXT, CSV, JSON or Markdown.

What you get

The right format in one move — no ad-filled converter, no copy-pasting between apps.

The client can't open your camera files

The annoyance

You shot RAW or exported TIFF. The client double-clicks and gets "can't open this file". Re-exporting everything means firing up your heavy editing software again.

The fix

Drop the folder → ⇧ Shift → JPG. Add Privacy Cleaner so your camera's serial number and the venue's location stay behind.

What you get

A gallery anyone can open, delivered the same evening.

Presets & pipelines

One drop, several steps, every file.

A preset is a saved recipe. Pick it once from the menu on the KhartTool bar, then drop one file or a whole folder: every file goes through every step, in order, and the results land next to the originals. Version 0.1.0 includes two ready-made presets.

Web Optimizer

Available now
Resize to 1920 px→ Remove hidden data→ Save as WebP

Great for

  • Online shops: turn a supplier's 15 MB product shots into light, fast-loading images in one drop.
  • Blogs and portfolios: stay under upload limits without opening an image editor.
  • Sharing a big batch: shrink 300 holiday photos before putting them in a shared drive.

Privacy Cleaner

Available now
Remove location & camera data→ Keep the same format

Great for

  • Marketplace listings: sell the couch without publishing where it sits.
  • Family photos: share kids' pictures in group chats without the home GPS pin.
  • Client work: deliver a gallery without your camera's serial number inside every file.
Coming in v0.2

Build your own pipeline

Soon you'll be able to chain any of KhartTool's actions into your own sequence: pick the steps, put them in order, give it a name. Then drop dozens or hundreds of files at once and walk away. The chore you repeat every week becomes one drag.

Pipelines people could build

Photographer's client gallery

RAW → JPG→Resize→Remove hidden data→Pack as ZIP

From a shoot folder to a ready-to-send gallery in one drop.

Scan it, send it

Photos → one PDF→Compress PDF→Remove PDF metadata

Phone photos of a contract become one small, clean PDF.

Social clip

Trim→Crop to vertical→Compress→MP4 or GIF

Every recording comes out ready for Reels, Shorts or a chat.

Voice notes and podcasts

Trim→Even out volume→Save as MP3

A folder of uneven recordings becomes a tidy, same-volume set.

These are ideas for v0.2, not features of 0.1.0. The steps and their order may change based on your feedback.

The most-requested ones ship first.

Coming next

Version 0.1.0 is just the start.

The next version is about making KhartTool fit your files and your habits. Here is what we are building, and your feedback decides the order.

Many more formats

The goal: nearly every file type you work with. More image, RAW, video, audio and document formats, plus more tools for each, all still offline.

Your own presets

Chain any actions into a named preset and run it on many files at once. See pipeline ideas.

A wheel set up your way

Choose which formats appear when you hold Shift and which commands appear when you hold Ctrl. Only what you actually use, one flick away.
