Twenty files. One upload.
ChatGPT, Claude and Gemini limit how many files you can upload. Merge your code, docs and data into one clean, AI-readable file — free, private, in your browser.
Twenty files. One upload.
Everything happens in your browser — code and documents never leave your device.
📂 Drop your files (or a whole folder's files) here
Code, markdown, CSV, JSON, TXT… combined into one clean, AI-readable document
Drop the files you want an AI to read — PDFs, Word docs, text, spreadsheets, code, images with text.
They are converted to clean text and joined in order, with a heading for each file, right here in your browser.
Press 📋 Copy all and paste into ChatGPT, Claude or Gemini — or ⬇️ Download .md to attach.
Check the token count shown under the result so you know it fits the model's context window.
💡 Tip: Put the most important document first — models pay the most attention to the start of a prompt.
Every AI chat has upload limits — a maximum number of files, or attachments that get skimmed instead of read. Twenty source files pasted one by one lose their structure, and the model loses the plot. Merging them into one structured document fixes both: the AI sees your whole project at once, with clear file boundaries and a tree overview at the top.
AIMerger's file merger runs completely in your browser. Your code and documents are never uploaded to us — important when you're working with client projects or anything under NDA. Drop in your files, get one clean markdown document with a file tree, per-file headers and a token estimate, then copy it straight into ChatGPT, Claude or Gemini.
Merge them first. Drop all your files into the combiner above — it produces one structured document with file headers and a tree, which you upload or paste as a single file, bypassing per-file limits.
Yes — this tool is fully client-side. Files are read and combined by your own browser; nothing is transmitted to our servers or anyone else's.
Any text-based file: source code in any language, Markdown, TXT, CSV, JSON, YAML, HTML, logs and more. Binary files like images and PDFs are automatically skipped.
Because it costs us nothing to run — your browser does the work. It's our way of showing how AIMerger builds tools: private by design, free where free is possible.
Everything on AIMerger brings things together — here is what pairs with this one.
