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.

Code & text files · PDF · Word .docx · Excel/ODS · images (with OCR) — combined into one AI-readable document
ℹ️ Merging gets around per-file upload limits, not the AI’s own limits: ChatGPT, Claude and Gemini still cap how much text they read at once (their “context window”). Check the token estimate, and trim if it is very large. Every file you add is listed with what was included — nothing is skipped silently.
Drop the files you want an AI to read — PDFs, Word docs, text, spreadsheets, code, images with text.
They are turned into clean text — PDFs and Word files by their text, spreadsheets sheet by sheet as CSV — and joined in order with a heading for each file, right here in your browser. Images and scanned pages can be read with OCR when you choose.
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. That avoids per-file upload limits, but not the AI’s own context limit: very large merges may be skimmed or cut off, so watch the token estimate.
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.
Text and code files in any language (Markdown, TXT, CSV, JSON, YAML, HTML, logs…), PDFs (their text — scanned pages can be read with OCR on your device), Word .docx files, Excel and OpenDocument spreadsheets (each sheet as CSV) and images (with OCR, when you choose). Videos, audio, archives and other binary files are listed as not included, with the reason.
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.
