This policy describes the technologies we use to store or access information on your device - for example, through cookies or similar methods. This enables us to realize the purposes listed here as soon as you access or use our website.
For the sake of simplicity, we use the term 'tracker' for all technologies used. The term 'cookie' is only used when we explicitly mean cookies in the browser.
Some processing with trackers requires your consent. You can revoke this at any time - you will find the options for doing so in this policy.
We use both our own trackers ('first-party') and third-party services ('third-party'). The lifespan of individual cookies depends on the provider - some end when the browser is closed, others remain stored for longer. Details can be found below or in the privacy policies of the respective third-party providers.
How we use trackers
1. functionality
This website uses cookies and similar technologies that are necessary to provide basic functions and requested services
.
Technical cookies
Runtime:
qConv_privacy_preferences: 1 year
qConv_theme: 1 year
qConv_lang: 1 year
qConv_theme_form: 1 year
qConv_sign_in_id: 1 month
qConv_sign_in_key: 1 month
Explicitly requested features also use a login session and locally saved colours, palette names and editing drafts in the colour collector. This storage serves the requested feature and does not grant analytics or advertising consent.
Optional preferences and filters
Additional hints, search filters, sorting and menu states (for example msg1, msg2, qc_filter*, qc_from, qc_to, gradient_menu and hide_code) are stored only after consent to our own device storage. Without it, controls continue to work but additional preferences are not stored persistently. Depending on the feature, cookies last up to one year.
2. measurement of success
We use trackers to measure visitor numbers and evaluate user behavior. This enables us to continuously improve our website
.
Matomo (self-hosted)
Self-hosted Matomo browser measurement (self-hosted) starts only after you consent to qConv.com’s own content measurement. Matomo cookies remain disabled. Our visitor and conversion statistics using qc_vid additionally require consent to device storage; qc_vid expires after at most one year and qc_ref after 90 days.
Anonymous server statistics
Separately from optional browser measurement, we count successful requests for public PHP pages only as daily totals by language and page category. No IP addresses, browser data, full URLs, search terms or visitor identifiers are stored. Totals are analysed separately in our self-hosted Matomo. Local daily counters are removed after at most 180 days. Anonymous totals in Matomo are retained for long-term annual comparisons. These are server requests, including possible bots, not unique visitors. This counter also respects the objection below and transmitted Do Not Track and Global Privacy Control signals.
Object to statistics
In addition to your choices in the Google dialog, you can block optional statistics in this browser.
Your objection is stored for one year in the necessary mtm_consent_removed cookie and applies to future requests in this browser. If you delete cookies, select this option again.
Your objection could not be saved persistently. Please allow storage of the necessary privacy preference.
3. marketing

First enter the color code to find the conversion and the best matching colors. After that, you can create palettes by clicking on and download color samples.
If you want to convert a color with transparency from web or UI design into a standard color code, you can convert RGBA to Hexadecimal. The four RGBA values — Red, Green, Blue, and Alpha (transparency) — are converted into a six-digit Hex code used in most design and development tools.
Converting RGBA to Hex lets you turn transparent colors into a format-independent, universally readable system. qConv automatically converts the RGB components into Hex values and can optionally display the extended eight-digit Hex code including transparency (#RRGGBBAA).
This conversion from RGBA to Hex is especially useful for web designers, UI developers, and branding agencies who need consistent color values across CSS, design software, and frontend code.
How does the conversion work?
During the conversion from RGBA to Hex, the three color values for red, green, and blue are first converted to hexadecimal. Each value between 0 and 255 is represented as a two-digit Hex number. The optional fourth value — transparency (Alpha) — is converted to an additional two-digit Hex value when using the eight-digit Hex format.
Example formula:
Red = decimal value / 16 → remainder * 16 = Hex code
Green = decimal value / 16 → remainder * 16 = Hex code
Blue = decimal value / 16 → remainder * 16 = Hex code
Alpha = transparency * 255 → Hex value (optional)
The result is a Hexadecimal code in the format #RRGGBB or #RRGGBBAA. qConv performs this calculation automatically and displays the resulting color along with a preview and alternative formats (e.g., RGB, HSL, LAB).
Example & application
Example: The color rgba(255, 0, 0, 0.5) — a semi-transparent red — converts to the Hexadecimal value #FF000080, where “80” represents 50% transparency. qConv instantly displays this RGBA to Hex conversion and lets you switch between six- and eight-digit formats.
Converting RGBA to Hex is perfect for web developers and UI designers transferring transparent colors from design programs into CSS, HTML, or frontend code. qConv ensures you always get the exact matching Hex value, even for gradients or semi-transparent elements.
Tip: Use the Hex conversion when unifying design systems. qConv also provides harmonious colors, shading variations, and contrast ratios for accessible design.
* Note:
qConv.com searches for the next matching color from the selected color palette. In most cases, there will be minimal or apparent color differences because there is not an exact match for every color.
The RGBA color model expands the classic RGB system (Red, Green, Blue) by adding a fourth value — the alpha channel. This represents transparency or opacity, allowing for the display of semi-transparent layers in digital media.
The red, green, and blue components each range from 0 to 255, while the alpha value is expressed as a decimal between 0 and 1. A value of 0 means full transparency, and 1 represents full opacity. This combination enables countless RGBA variations and is widely used in web design and modern user interfaces to create light, depth, and layered effects.
Usage
RGBA is a core part of modern front-end development. In CSS, SVG, and Canvas elements, the alpha channel is used to control transparency for shadows, overlays, buttons, or hover states. UI-prototyping tools like Figma or Adobe XD also use RGBA to create realistic depth and visual transitions.
Because RGBA is based on the RGB color space, it’s ideal for digital display but not suitable for print. When exporting to CMYK or Pantone®, transparency is mathematically flattened or removed, so designers should review transparency effects before conversion.
Tips for Designers & Agencies
Use RGBA colors to achieve subtle light and shadow effects in your web projects. An alpha value between 0.2–0.5 works perfectly for overlays or glassmorphism effects in modern UI design.
With qConv, you can precisely convert any RGBA color into other color systems and see how transparency affects perception. This ensures consistent designs across digital and print workflows.
The hexadecimal color system is one of the most widely used methods for representing colors in digital media. It combines the three primary colors — Red, Green, and Blue — and expresses their values using hexadecimal notation. Each color component is represented by two characters, forming a six-digit code such as #FF5733.
The first two digits represent red, the middle two green, and the last two blue. The range of each pair goes from 00 to FF, corresponding to 0–255 in decimal values. With this structure, there are a total of 16,777,216 possible hexadecimal colors, covering nearly the full visible RGB color range.
Usage
Hexadecimal color codes are the standard for web design, front-end development, and digital branding. They are supported in HTML, CSS, SVG, and nearly all design applications. HEX values are compact, easy to read, and ideal for defining precise colors in digital interfaces, animations, and style sheets.
In professional design workflows, HEX values are often used alongside RGB or HSL to ensure consistency across screens. Designers can also use HEX-to-RGB conversions to fine-tune colors for print simulations or cross-platform visual harmony.
Tips for Designers & Developers
When creating color palettes, group HEX values that share visual harmony — for instance, complementary or analogous combinations. Use lowercase HEX (e.g. #a1b2c3) for better readability and code consistency.
With qConv, you can instantly convert HEX colors into RGB, CMYK, or Pantone® equivalents, generate gradients, or explore related shades and tints. Perfect for designers and developers seeking pixel-perfect color accuracy.
To be able to save color palettes, a registration is required.
As a guest, you can collect and download colors in the color collector. Activate qConv Start for free to save color palettes permanently and manage the colors in each palette.
