Our Mission
PixNmerge exists because most "free" online file tools are not really free. They ask you to create an account, upload your images to a remote server, wait for a cloud process to finish, and then download the result — all while logging your activity and using your files to improve their commercial products. We think that's the wrong trade-off.
Our mission is simple: give everyone access to fast, reliable file conversion and utility tools that work entirely inside the browser, so your files never leave your device. No accounts, no uploads, no waiting. Just open the tool, pick your files, and get results in seconds.
How PixNmerge Works
Every tool on PixNmerge runs locally using modern browser APIs. When you convert a JPG to PNG, for example, the image is loaded into an HTML5 Canvas element inside your browser tab. The canvas redraws the image at the specified quality, then exports it as a new file — without a single byte traveling over the network.
More complex operations use additional Web Platform features:
- Web Workers — heavy batch operations (compressing 20 images at once, for example) run in a background thread so your browser stays responsive.
- FileReader API — reads your selected files into memory safely, scoped to the current browser session. The data is discarded the moment you close or refresh the tab.
- JSZip — a well-tested open-source library that creates and extracts ZIP archives entirely in JavaScript, with no native binary dependencies.
- WebRTC / PeerJS — powers the Send File feature, enabling direct peer-to-peer transfers between two devices on the same session without routing files through a server.
The site is built with Angular and pre-rendered at build time (server-side rendering), which means pages load instantly and search engines can index all content properly — even for users on slower connections.
What You Can Do with PixNmerge
Image Conversion
Convert between the most common raster image formats: JPG/JPEG to PNG, PNG to JPG, WebP to PNG, and BMP to PNG. Each converter lets you control output quality with a slider, supports batch processing of up to 20 images at once, and lets you download results individually or as a single ZIP archive. Use the JPG to PNG converter when you need a lossless copy of a photograph, or PNG to JPG when you need to reduce file size for web publishing.
Image Resizing
The Image Resizer supports three resize modes: choose from a set of common presets (thumbnail, HD, 4K, Instagram square, Facebook cover, and more), enter custom pixel dimensions, or resize by percentage. Aspect ratio locking prevents accidental distortion, and batch mode handles entire photo sets in one pass.
Image Compression
The Image Compressor offers preset quality levels (High, Medium, Low) and a custom quality slider (10–100 %). It also includes optional dimension limits so oversized images are downscaled and compressed in one step. Ideal for preparing images for websites, social media, email attachments, or cloud storage.
ZIP Archive Tools
The ZIP Creator bundles any collection of files — images, documents, or mixed content — into a named ZIP archive with a single click. The ZIP Extractor unpacks ZIP files directly in the browser and lets you preview file names before downloading. Both tools process archives locally with no size limit imposed by a server.
File Size Calculator
The File Size Calculator quickly estimates the size of an image after format conversion or compression without actually converting it. Useful for planning storage, bandwidth, or email attachment budgets before you commit to a format change.
File Format Guide
The File Format Guide is an educational reference covering image, document, video, and audio formats. Each entry explains the format's compression method, typical use cases, advantages, and limitations — helping you make the right choice for your workflow.
Send File (Peer-to-Peer)
Send File lets you share files directly with another device using a 6-digit code. The sender generates the code, the receiver enters it, and the transfer happens over an encrypted WebRTC channel — no cloud intermediary, no file size limit imposed by an email provider or messaging app, no account required on either end.
Privacy and Trust
Because file processing happens in your browser, PixNmerge never sees your files. We have no file storage, no file-processing servers, and no access to the content you work with. This isn't a marketing claim — it's how the architecture works. You can verify it yourself by opening your browser's Network tab while using any tool: you'll see no outbound requests carrying your file data.
We do use Google Analytics (anonymised aggregate reporting) to understand which tools are most used and where errors occur. We display advertising through Google AdSense to keep the service free. Our Privacy Policy documents exactly what is collected and how you can opt out.
We comply with GDPR principles: we collect the minimum data needed, we don't sell personal data, and we provide a contact address for data-related enquiries.
Who PixNmerge Is For
- Photographers and designers who need quick format conversions or batch resizes without opening heavy desktop software.
- Web developers who need to optimise images for production without setting up a build pipeline tool.
- Content creators and social media managers resizing photos to platform-specific dimensions dozens of times a week.
- Small businesses managing product images for e-commerce stores, needing compressed images that don't slow down page loads.
- Students and researchers working with scanned documents or image datasets who need lightweight tools that don't require software installation.
- Remote or hybrid teams using Send File to share large files between devices without going through IT-managed file-sharing services.
PixNmerge works on any modern browser — Chrome, Firefox, Safari, and Edge — on desktop and mobile. No installation, no browser extension, no app download required.
Frequently Asked Questions
Is PixNmerge really free?
Yes. All tools are free to use with no hidden tiers or credit limits. We keep the service free by displaying ads. If you use an ad blocker, the tools still work — we don't gate features behind ad views.
Are my files safe when I use PixNmerge?
Your files never leave your device. All processing happens inside your browser using JavaScript and the HTML5 Canvas API. We have no server infrastructure that receives or stores file content. Once you close the browser tab, the data is gone.
Which image format should I use — JPG or PNG?
Use JPG for photographs and images with many colours where a small file size matters more than perfect quality (web pages, social media). Use PNG when you need a transparent background, pixel-perfect quality, or a lossless copy of an image you'll edit further. Use WebP if your target platform supports it — it offers the best compression-to-quality ratio of the three.
Does PixNmerge work offline?
Most tools work after the initial page load because all processing is client-side. However, the Send File feature requires an internet connection for the WebRTC signalling handshake. Loading the site itself requires connectivity the first time you visit; subsequent visits may partially work from the browser cache.
