How to Use Quarkova

Free · No account · No install

Quarkova is built around a single philosophy: your tools should work immediately, without friction. There's no sign-up page, no email verification, and no subscription paywall. Navigate to any tool and start processing files within seconds.

Browser-based image tools (Image Compressor and PNG → WebP Converter) use the HTML5 Canvas API to process your files entirely within your browser tab. Your images are never transmitted to any server. This means zero upload time, zero bandwidth cost, and complete privacy — even on a slow mobile connection.

Server-side PDF tools (Images to PDF and PDF Splitter) require a brief server round-trip because PDF manipulation depends on the PHP Imagick library. Your files are handled securely, processed in a temporary directory, and deleted the moment your download completes. There is no persistent storage — ever.

All tools are fully responsive and tested on desktop (Chrome, Firefox, Edge, Safari) and on mobile (iOS Safari, Android Chrome). No browser extension or plugin is required.

Choose your tool

Click any tool in the navigation bar. Each tool page explains exactly what it does and which file types it accepts.

Upload or select your file

Use the file picker to select your image or PDF. For image tools, the file stays local. For PDF tools, it's sent securely to the server.

Adjust settings

Use quality sliders (image tools) or page range inputs (PDF tools) to configure exactly the output you need.

Download your result

Click the action button. Your file is ready in seconds. For PDF tools, server files are deleted automatically after download.

Frequently Asked Questions

Do I need to create an account?

No. All tools are accessible immediately without registration, login, or subscription. Just open the page and start working.

Are my files stored on Quarkova's servers?

Image tools process files entirely in your browser — nothing is ever sent to the server. PDF tools use a temporary server directory that is wiped immediately after each download.

What browsers are supported?

Chrome 90+, Firefox 88+, Edge 90+, Safari 14+, and their mobile equivalents. The Canvas API used by image tools is available in all modern browsers.

Is there a file size limit?

For browser-based image tools, limits are determined by your device's RAM. For server-side PDF tools, the server's upload_max_filesize applies (typically 8–16MB in Laragon).

Can I use Quarkova on my phone?

Yes. The interface is fully responsive and tested on iOS Safari and Android Chrome. You can compress images and split PDFs directly from your smartphone.

Why are there advertisements?

Carefully placed, clearly labelled ads help us keep Quarkova free and maintained. We use only non-intrusive placements — never pop-ups or auto-playing videos.

How accurate is the image compression?

Quality is determined by the JPEG encoding factor you choose. At 80%, file sizes typically drop 50–65% with no visible quality difference at normal viewing sizes.

Will more tools be added?

Yes. Planned additions include SVG optimiser, GIF to WebP converter, PDF merge, and a bulk image resizer. Subscribe to the blog for updates.
