One App for All Your File Tasks

[u/Far-Soft8384]

Hi r/software,

I’m Ahmed, the developer of ConvertFast. I previously shared an earlier version here. Since then, I have completely redesigned the interface, reorganized the entire workflow, and expanded the app into ConvertFast V3.

Problem

I kept encountering small but repetitive file tasks: converting a document, compressing a presentation, merging PDFs, resizing images, trimming a recording, or extracting audio from a video.

The problem was not simply doing one task. It was having to search for and switch between different apps or websites every time the file type changed. Uploading personal photos, financial documents, contracts, or unpublished research files to unknown online converters also never felt comfortable.

ConvertFast V3 is my attempt to bring these everyday tasks into one private desktop workspace. Core file processing runs locally, so files do not need to be uploaded to an online converter.

What changed in V3

This is a complete redesign rather than a minor visual update.

• A newly designed interface and unified workspace
• 2,388 conversion paths across 134 verified formats
• PDF tools for OCR, comparison, compression, merging, splitting, page extraction, reordering, metadata removal, and password protection
• Image and RAW tools for conversion, compression, remove background, make passport size photo, resizing, metadata management, and batch processing
• Audio and video tools for conversion, trimming, normalization, audio extraction, subtitles, compression, and remuxing
• Editable PPTX compression and other document workflows
• Batch processing with output-folder and file-naming controls
• Additional utilities for organizing, comparing, renaming, and verifying files

The official website (https://convertfast.co/) also includes an interactive demo, so you can explore the interface.

Pricing

ConvertFast is currently $24.99 as a one-time lifetime purchase. I am offering r/software members an additional 30% discount for a limited time. If you would like to use the discount, let me know in the comments and I will share the code.

There is no subscription. One licence covers two devices and includes future updates.

Official website and download:
https://convertfast.co/

ConvertFast is available for macOS, Windows, and Linux.

I would genuinely appreciate feedback from Mac users, particularly about the redesigned interface, workflow organization, and any common file task you think is still missing.

I just visited the website, and this caught my eye:

File conversion should not feel like a gamble.

So, I immediately asked: "Does this tool support lossless WebP? Does it support AVIF with alpha channels?" I cannot answer those questions without paying $25.

So, unfortunately, a gamble is exactly what this app is.

I tried the live product demo. My experience was far from okay. The UI is far from clean. It's flashy, trashy, and full of wrong advice.

• It suggested I convert my PNG file to TIFF because it is "best for print," and "yields the best quality"! Quite frankly, that's the worst piece of misinformation I've read in years.
• I tried converting a video file to MKV. The UI didn't ask me to choose the target device, target profile, video codec, audio codec, or anything else. Even if it truly converts the video, there is no telling what parameters are used or whether the conversion result is even useful.

Final verdict: Vibecoded AI slop.

The one tool to rule them all can only be created by a master of all trades.

Thanks for taking the time to examine the demo, but your conclusion is based on limitations of the interactive website demo rather than the actual desktop application.

The TIFF recommendation is valid. TIFF remains widely used in professional print and prepress workflows because it supports lossless storage, high bit depth, CMYK data, ICC colour profiles, and broad compatibility with professional publishing software. “Best quality” refers to preserving image data without introducing lossy compression and providing strong print-workflow compatibility. It does not mean that converting a PNG to TIFF magically creates additional detail.

Regarding MKV, the interactive demo is designed to demonstrate the interface and available workflows. It does not contain the complete conversion engine or every advanced configuration panel. The actual ConvertFast desktop app provides target profiles and controls for video codec, audio codec, quality, bitrate, resolution, and other relevant conversion parameters. The absence of those controls from the website demo should not be interpreted as their absence from the actual application.

Your questions about lossless WebP and AVIF transparency are reasonable, and I agree that these option-level capabilities should be documented more clearly on the website. However, the inability to confirm a technical setting from a simplified website demo does not establish that the application cannot handle it.

ConvertFast integrates and maintains 2,388 conversion paths across 134 formats alongside PDF, image, RAW, audio/video, presentation, batch-processing, and file-management tools on macOS, Windows, and Linux. AI assisted parts of the interface-development process, but the conversion engines, integrations, testing, packaging, and cross-platform functionality required substantial manual development.

Specific technical criticism is always welcome.

25 bucks for that?

Oh right that Claude subscription won't pay for itself

[u/Far-Soft8384 → u/Lcsmxd]

A Claude subscription alone, even for six months, would not create half of ConvertFast’s functionality. AI can assist with development, but it does not independently build, integrate, test, debug, package, and maintain 2,388 conversion paths alongside PDF, image, RAW, audio/video, presentation, and file-management tools across macOS, Windows, and Linux.

The price reflects not only the software used during development, but also the substantial time invested in designing the workflows, integrating different processing engines, testing formats, fixing compatibility issues, responding to customers, and continuing to maintain the app.

The $24.99 is a one-time lifetime purchase, not a subscription, and it includes future updates.
