GitHub Contribution Graph Wallpaper Maker

How the GitHub contribution graph wallpaper works

The tool follows a short path from a public username to a downloadable image. It retrieves dated contribution counts, checks that the response contains usable dates, maps each day to one of the graph's activity levels, and paints the calendar onto a wide canvas. The PNG export has fixed dimensions, so it remains sharp on a 4K screen and can also be cropped for other desktop sizes. The page does not query private repositories or show repository names.

The browser requests data only after submission. On success, it replaces the sample, reports the date count and visible contributions, and enables download. The source graph defines activity; this tool cannot recalculate GitHub rules, repair missing days, or infer work absent from the public calendar.

1. Enter a usernameUse the public profile name, not an email address or secret credential.
2. Choose a period and palettePick the rolling year or current calendar year, then select the background and heatmap colors.
3. Load and inspectConfirm the account name, visible contribution count, date window, and preview before exporting.
4. Save the PNGDownload the 3840 × 2160 file and set it as your desktop background using your operating system's fit option.

Choose a palette that works on your display

The palette changes both the wallpaper background and the four contribution intensity steps. Midnight keeps a dark green base and a warm highlight; Paper uses a light surface for bright rooms; Forest and Ocean keep lower contrast around the grid; Sunset adds a warmer accent. These choices affect presentation only. They do not change dates, counts, activity levels, or the profile data returned by the provider.

Keep the calendar readable behind desktop icons: squares have consistent gaps, month labels sit above the grid, and the total stays separate. Check the image at normal scale before setting it as a background. If shortcuts cover the left edge, adjust the operating system's crop or fit setting.

What 4K means for this wallpaper

The exported canvas is 3840 × 2160 pixels, the common UHD 4K frame for a 16:9 display. A larger source gives the operating system room to scale down on many 1080p and 1440p screens. It does not add detail to the contribution calendar; it draws squares and text at a size that avoids a blurry screenshot. Creating a PNG can use extra memory on a phone or older laptop.

The preview is scaled to fit the page; the downloaded file keeps the full dimensions. Check its properties if it looks soft. The tool does not compress a second copy or guarantee that each operating system uses the same crop.

Public data, privacy, and source limits

This generator is for public GitHub profiles. It sends the submitted username to the community-maintained endpoint below and receives a visible calendar as JSON. It has no credential field: do not enter passwords, tokens, email addresses, or private values. The calendar may include an anonymized activity signal when the profile owner enables that setting, but it does not expose private repository names.

The endpoint is a third-party service rather than an official GitHub API. Its response can be delayed, rate limited, incomplete, or temporarily unavailable. Treat the generated wallpaper as a visual copy of the data returned at that moment, not as an official record or proof of work. If an activity day is absent, first compare the profile's contribution calendar and GitHub's own contribution rules. A wallpaper generator cannot correct commit email, branch, fork, private-visibility, or timezone issues. The downloaded image is static and can become outdated as new activity appears.

Use the wallpaper where a static image makes sense

A desktop background can hold a personal activity visual without replacing project evidence. The grid shows a rhythm across the chosen period; the total summarizes public data. It is not a productivity grade or proof of work. Contribution events do not explain their context or quality.

A 4K wallpaper is not optimized for a narrow README or a frequently updated page. Use a live image when freshness matters. Our contribution PNG guide covers static publishing; the graph rules guide explains missing activity.

1. Desktop backgroundUse the 4K PNG for a personal workspace and choose fill, fit, or center according to your display.
2. Portfolio or slideCrop a copy for the frame and add nearby text that explains the period and what the activity represents.
3. Profile READMEPrefer an updating image when freshness is important; a downloaded wallpaper will not refresh itself.

Fix common generation problems

If the username is rejected before a request begins, check that it contains only a GitHub-style profile name with letters, numbers, or hyphens. The form rejects spaces, a leading or trailing hyphen, and credential-like values. If the provider says the account cannot be found, confirm the spelling and that the profile is public. A valid username can still fail when the community endpoint is down or enforcing a temporary rate limit; wait and retry rather than submitting the form repeatedly.

If the calendar looks sparse, compare it with the profile's visible graph; the response only covers the selected period and activity the source can see. If download fails, check browser download settings. On a low-memory device, close large tabs and retry. Live totals stay hidden until a real response replaces the labeled sample.

What the wallpaper maker does not do

The maker does not sign in, read private repository names, use a token, or upload the generated file. It does not fetch a profile biography, avatar, repositories, or followers. Its output is one user-selected public calendar rendered as a local PNG.

A square records activity in the upstream graph's format, not its quality or context. Check GitHub's rules when days are missing. Use GitHub City for interactive 3D exploration and the contribution PNG guide for static publishing.
