Draw a logo for your coin, right here in your browser.

A free, simple paint program for making the little picture people see next to your coin, with a check that it still looks clear when it is shown tiny.

For the tech-minded: exports a 400×400 PNG and a metadata JSON file, makes a SHA-256 fingerprint, and can optionally timestamp it on Solana. Pixelpress never creates, launches or mints a coin.

How it works in 3 steps

  1. step1.exe

    You give it: a drawing made here, or a picture you already have.

  2. step2.exe

    It checks: your logo stays clear at the tiny sizes wallets use.

  3. step3.exe

    You get: a clean logo file and info file, ready for any launchpad.

Free, and no wallet needed. Nothing is moved or charged unless you choose to sign the optional timestamp in your own wallet.

02

Will it still look clear when tiny?

What this does: shows your logo at the small, round sizes wallet apps use, and scores how clear it stays.

Most people see a coin logo at 32 to 48 pixels, cut into a circle, on a dark or light screen.

Small-size fidelity-How much of the 400 px detail is still there after shrinking to 32 px and back (1 − normalised error).
Round-crop safety-Share of your drawn pixels that sit inside the inscribed circle, which is what round avatars keep.
Figure / ground contrast-WCAG contrast ratio between your two most-used colours. 3:1 or more reads well at small sizes.
Colours in use-Distinct colours after rounding to 4 bits per channel.

Press "Check my logo" or "Try an example" to get a verdict.

03

Does it stand out next to real coins?

What this does: puts your logo into today's live list of popular Solana coins, at the size traders really see.

The list comes live from Jupiter, a big Solana trading site. Does yours stand out or blend in?

    Is the name already taken?

    What this does: searches live Solana coins to see whether someone already uses your ticker.

    Searched live in Jupiter's list of Solana coins on mainnet (the real network, not a test one).

    A fingerprint for your picture

    What this does: turns your picture into a unique code; change a single dot and the code changes.

    Technically a SHA-256 hash, of two things: the exact PNG file and the raw pixels. The pixel code survives re-saving; the file code proves one exact file.

    The picture on the left is drawn from the code, so two different logos almost never look alike here.

    What this does: tells you whether an image file is the same picture as the one on your canvas.

    Checks a copy of your current canvas against itself.

    Pick a file to compute its hashes.

    Download your logo files

    What this does: gives you the logo image plus the small info file most launchpads ask for. Nothing is uploaded.

    For the tech-minded: a 400×400 PNG and a token metadata JSON in the common Metaplex shape, checked against the on-chain length limits. Upload the PNG wherever you host files and paste its link into image.

    Timestamp it on Solana (optional)
    What this does: writes your picture's fingerprint into a public note on Solana, signed by you, as dated proof you had it first.
    The note uses the Solana Memo program. No coin is created and no money moves; you only pay the network fee of about 0.000005 SOL.

    Questions
    
  
    
    
    What is this, in one sentence?
    Pixelpress is a free paint program in your browser for drawing a coin's logo, checking it looks clear when small, and downloading it as files.
    
    
    Is it safe? Does it touch my money?
    Drawing, checking and downloading need no wallet and never touch your money. Pixelpress never asks for your seed phrase and cannot move funds. The one optional thing that uses your wallet is the timestamp: you see exactly what it does first, your own wallet asks you to approve it, it moves no coins, and it costs a network fee of about 0.000005 SOL. It is an independent tool with no audit, so only sign what you have read.
    
    
    Does Pixelpress create or launch my coin?
    No. It exports a PNG and a metadata JSON file. It has no mint, launch or swap function, and never will. You take the files to whatever launchpad you choose.
    
    
    Where is my drawing stored?
    In this browser tab only. Your last canvas is also kept in this browser's local storage so a refresh does not wipe it. Nothing is uploaded to us; there is no server-side storage at all.
    
    
    Why two hashes?
    The PNG file hash proves one exact file. But re-saving the same picture can change the file bytes while the pixels stay identical, so the pixel hash (SHA-256 over the raw RGBA buffer) is the one that survives. The stamp records the pixel hash.
    
    
    What does the Memo stamp cost and what does it do?
    One Solana network fee, usually 5,000 lamports (0.000005 SOL). It writes a short public text to the chain via the SPL Memo program, signed by your wallet. It moves no tokens and grants no rights; it is a timestamped public note.
    
    
    Is the lineup data real?
    Yes. It is Jupiter's live top-trending list for the window you pick, fetched from your browser. Token icons load from wherever each project hosts them.
    
    
    Are the legibility numbers scientific?
    They are honest measurements of your pixels (error after downscaling, pixels inside the circle, WCAG contrast of your two main colours). Whether a logo is good is still your judgement.
