Practical Tips & Guides
Short, useful guidance to help you get better results from the tools.
How to compress images without visible quality loss
Most photos carry far more data than a screen can display. A few habits keep them sharp while cutting their weight dramatically.
- Resize first. A 4000-pixel photo shown at 800 pixels wastes bandwidth — reduce dimensions before anything else.
- Choose the right format: JPG or WebP for photos, PNG for screenshots and graphics, SVG for logos.
- Use moderate quality settings. Around 70–85% is usually indistinguishable from the original to the eye.
- Run the final file through the Image Compressor, or use the dedicated JPEG Compressor and PNG Compressor.
Working with PDFs: merge, split, convert and compress
PDF is the standard for documents you want to look the same on every device. A typical clean-up follows a simple order.
- Remove unneeded pages with Delete PDF Pages or keep only selected ones with Extract PDF Pages.
- Fix orientation using Rotate PDF, then combine documents through Merge PDF.
- Need it editable? Use PDF to Word, PDF to Excel Converter or PDF to Text Converter.
- Finish with PDF Compressor so the file is small enough for email or an upload form.
Choosing the right audio and video format
MP3 is the safest choice for sharing, WAV is for editing, and M4A gives excellent quality at small sizes. For video, MP4 with H.264 plays almost everywhere.
- Convert editing masters with the WAV to MP3 Converter before sharing.
- Pull the sound out of a clip using the MP4 to MP3 Converter or Video to MP3 Converter.
- Switch camera or screen-recording files with MOV to MP4 Converter or MKV to MP4 Converter.
- Keep messaging uploads light with the Video Compressor.
Time zone conversion made simple
Scheduling across regions is easier when you know how the abbreviations work. UTC is the global reference and does not change with the seasons, while US zones shift for daylight saving time.
- PST and EST are standard-time names; in summer the same regions observe PDT and EDT.
- GMT and UTC are treated as the same reference for everyday scheduling.
- Compare any two places with the Time Zone Converter, or use quick pairs like EST to PST Converter and UTC to EST Converter.
- Count only working days between deadlines using the Business Days Calculator.

Free Online Tools — All in One Place
Welcome to ToolzNova, a growing library of more than 262 free online tools built for people who want quick answers without installing software. Whether you need to convert an image, merge PDFs, compress a video, work out a loan payment or convert a time zone, you can do it here in a few clicks. There is nothing to download, no account to create and no watermark on your results.
We built ToolzNova around one idea: everyday file and calculation tasks should be fast, clear and free. Instead of hunting for a different website for each job, you can find image converters, PDF utilities, audio and video tools, finance calculators, maths helpers, unit converters and text utilities in a single, consistent place.
Image Conversion and Optimisation
Our image tools cover the formats people use every day. Convert JPG to PDF for documents, JPG to WebP for faster websites, and HEIC to JPG to open iPhone photos anywhere. Need the reverse? Try PNG to JPG, WebP to PNG or AVIF to JPG. Designers can also handle PSD to PNG and DNG to JPG files without professional software.
PDF and Document Tools
The PDF toolkit lets you merge, split, rotate and extract pages from PDF files, convert them to Word, Excel or JPG, and create PDFs from Word, Excel, PowerPoint and HTML files. Together they cover the most common paperwork jobs at school, at work and at home.
Compression for Every File Type
Large files are slow to send and expensive to store. The Image Compressor, PDF Compressor, Video Compressor, MP3 Compressor and GIF Compressor reduce size while keeping the result usable. Targeted pages such as Compress PDF to 1MB and Compress Video to 25MB help when a website or messaging app enforces a strict limit.
Calculators for Money, Maths and Health
From an EMI calculator and compound interest calculator to a scientific calculator, standard deviation calculator and BMI calculator, ToolzNova gives you clear results you can use straight away. Results are estimates for planning and learning and should not replace professional financial, medical or academic advice.
Your Privacy Matters
Our file tools are designed to run in your browser using technologies such as the Canvas API, Web Audio API and PDF.js, which keeps your files on your device while they are being processed. We also publish our Privacy Policy, Terms of Service and Cookie Policy so you can see exactly how the site works.
