Choose File - One Drop, Every Tool

What is the Choose File page?

Choose File is the universal entry point to PixNmerge. Drop any file — an image, a ZIP, a document — and we surface only the operations that actually make sense for that file type. No more guessing which tool you need: pick the file first, then pick what to do with it.

Behind the scenes it's the same fast, in-browser engine that powers our dedicated tool pages (JPG to PNG, PNG to JPG, WebP to PNG, BMP to PNG, image resizer, image compressor, ZIP creator, ZIP extractor, peer-to-peer Send File). Nothing is uploaded to a server — your file is read, processed, and written entirely on your own device.

How to use it
  • Step 1: Drop a file (or several) into the upload area, or click to browse.
  • Step 2: Pick an operation from the list of options the page shows for your file.
  • Step 3: Adjust the settings (output format, quality, dimensions, archive name, password, etc.).
  • Step 4: Click the action button. Download the result when it appears.
Why use Choose File instead of a dedicated tool?
  • You have a mixed batch of files and want one place to handle them.
  • You don't know in advance whether you need to convert, resize, or compress.
  • You want to chain operations without bouncing between pages.
  • You need to send the file to someone else after processing it.

Operations available from this page

Convert format

Switch images between JPG, PNG, WebP and BMP in your browser. Useful for cross-app compatibility (e.g. PNG for transparency, JPG for smaller photo files, WebP for web).

Resize

Pick a preset size (HD, social profile, thumbnail), enter custom width and height, or scale by percentage. Aspect ratio is locked by default.

Compress

Reduce image file size with a quality slider, with an optional max-dimension cap so an oversized photo also gets resized down before encoding.

Create ZIP

Bundle the selected files into a single ZIP archive with a custom name. Existing ZIPs in the selection are nested as-is.

Extract ZIP

Unpack one or more ZIP archives, including password-protected ones. Download files one by one or all at once.

Send (peer-to-peer)

Hand off to the Send File flow: generate a 6-digit code, share it, and the receiver downloads the file directly browser-to-browser.

Privacy & Performance

🔒
100% in-browser processing

Conversion, resizing, compression and ZIP packing all run locally using the Canvas and File APIs. Your file never leaves your device, so there's nothing for us (or anyone else) to leak.

⚡
No upload wait

Because there's no upload step, processing starts the moment you click. Speed is bound by your CPU, not your network.

🆓
Free, no signup

No account, no email, no watermarks, no per-file limits. Open the page, drop a file, get a result.

📱
Works on any device

Runs in any modern browser on desktop, laptop, tablet or phone. The same page works the same way everywhere.

Frequently asked questions

What file types can I drop here?

Images (JPG, JPEG, PNG, WebP, BMP), ZIP archives, and any file you want to bundle into a ZIP or send to another device. The page shows only the operations that apply to what you dropped.

Is there a file-size limit?

There's no hard limit imposed by us — the practical ceiling is your device's available memory, since processing happens on your machine.

Does it work offline?

Once the page is loaded, all operations except Send (which needs a connection for the peer-to-peer handshake) keep working without internet.

Should I use this page or the dedicated tool page?

Either works. Dedicated pages (e.g. JPG to PNG, Image Compressor) are slightly faster to land on if you already know what you want. Choose File is better when you have multiple files of mixed types or aren't sure which tool you need.
