Guides
Before using a tool, it can help to understand the lay of the land: which format fits your case, what's kept and what's lost when converting, how operations that sound alike actually differ, how QuickToolio processes your files, and what real limits exist before you start. That's what these guides are for: background resources, not a step-by-step instruction list.
How QuickToolio processes your files in the browser
Explains what it actually means for a tool to "process in the browser", what data can travel over the internet (and what doesn't), and how your device's memory sets the practical file-size limit.
- Processing in the browser
- What data travels and what doesn't
- Memory and device limits
JPG, PNG, WEBP, AVIF, GIF or SVG: which image format to choose
Compares JPG, PNG, WEBP, AVIF, GIF and SVG so you can pick the right format based on transparency, compression, animation or scaling, and tells apart converting from compressing or resizing.
- JPG, PNG, WEBP, AVIF, GIF and SVG
- Transparency and animation
- Converting, compressing or resizing
Document and archive formats: which one to choose and what each one keeps
Helps you choose between DOCX, PDF, TXT, HTML, Markdown, EPUB and ODT, and between ZIP, RAR, 7Z, TAR and GZ, explaining what each conversion keeps and what can get lost along the way.
- DOCX, PDF, TXT, HTML, Markdown, EPUB, ODT
- ZIP, RAR, 7Z, TAR, GZ
- What's kept and what's lost
How to reduce a PDF's size and what changes when you edit it
Explains what takes up space in a PDF, what the compressor really reduces (and why a text PDF barely shrinks) and what merging, splitting, protecting or converting to images keep or lose.
- Why PDFs are heavy
- Compression profiles
- Merge, split and protect
Audio and video formats: quality, size and compatibility
Compares MP3, AAC, OPUS, FLAC and WAV, recommends bitrates by use, and clears up container versus codec for MP4, MOV, MKV and WEBM.
- Lossy and lossless
- Which bitrate to choose
- MP4, MOV, MKV and WEBM
AI photo editing in the browser: how it works and what to expect
Details the resolution the in-browser AI models work at and what results to expect when removing backgrounds, erasing objects, upscaling or anonymising faces.
- Models and downloads
- Resolution limits
- When not to use AI
How loan and mortgage payments are calculated
Breaks down the payment formula with calculated examples: why early payments are mostly interest and how much the term and rate change the total.
- Payment formula
- Interest versus principal
- Term, rate and APR
Each guide links to real QuickToolio tools, with their capabilities and limits described based on how they actually work, not in generic terms. The links go to tools available in your language.
