What PixelEditor is
PixelEditor is a collection of image utilities that run inside your web browser. Resize, crop, rotate, compress, convert between formats, check dimensions, strip metadata, and do any of those to a folder of images at once. Each tool has its own page and its own address, so the one you keep needing can be bookmarked and opened directly.
There is no account, no sign-in, no watermark, no paid tier that unlocks the real version, and no upload step. You open a page, drop in a file, and the work happens on your own machine.
Why local processing
The ordinary way to build an online image tool is to accept an upload, process the file on a server, and send the result back. It works, and it quietly creates a set of problems that have nothing to do with images.
Your file leaves your device. It is transmitted across a network, written to a disk you do not control, and held there for however long that service decides. It can be logged, backed up, retained after deletion, examined by staff, exposed by a misconfiguration, inherited by whoever buys the company, or handed over on request. None of that requires bad intent from anyone — it is simply what having your file makes possible.
Meanwhile the browser on your device has been able to decode, redraw and re-encode images for years. It is the obvious place to do this work: the file is already there, no network round trip is needed in either direction, and a server that never receives your photograph cannot lose it. That is the entire premise of this site.
The practical benefits follow from the same design. Nothing waits in an upload queue, large files are not limited by someone else’s bandwidth allowance, and once the page has loaded the tools keep working with the network disconnected.
How it is built
Each tool reads your file into the page’s memory, decodes it into an image, redraws it onto a canvas with whatever change you asked for, and encodes the result back into a file. The browser’s own graphics and codec implementations do the heavy lifting; heavier jobs are handed to a Web Worker, which is a background thread in the same tab, so the interface stays responsive while a large photograph is processed.
The site itself is a set of static files — HTML, CSS, JavaScript and fonts. There is no application server, no database and no API. That is not a detail of the hosting arrangement; it is the reason the privacy claims on this site can be specific. A backend that does not exist cannot store your images.
A few smaller decisions follow the same logic. Fonts are downloaded at build time and served from this site, so no font provider sees your visit. The metadata parser and the ZIP builder are bundled into the site and loaded from it on demand rather than pulled from someone else’s content delivery network. Output formats are offered only after the browser has been asked to encode a tiny test image and has produced a valid result — which is why AVIF appears on some devices and not others, instead of failing silently after you have processed fifty files.
What we claim, and what we do not
Plenty of tools advertise “100% private” and “zero data collection”. Those phrases are easy to write and almost impossible to support, so they are not used here. What is true is narrower and checkable:
- Your images are processed in your browser and are not transmitted to us. There is no code in this site that sends file data anywhere.
- The site sets no cookies, runs no analytics and makes no third-party requests.
- Nothing you process is stored — not on a server, and not in your browser’s storage either.
And what we will not claim:
- That nothing is recorded anywhere. A web host serves these pages and, like every web host, can log the request — IP address, timestamp, user agent. The Privacy Policy says so.
- That your device is secure. Malware, a hostile browser extension or someone reading over your shoulder are outside anything this site can affect.
- That a target file size is guaranteed, or that metadata removal is forensically complete. The tools report what they measured and what they could verify, including when the answer is “not quite”.
The same discipline applies to the tool pages: if a page describes a behaviour, that behaviour is in the code. Where a limit exists — fifty files per batch, first frame only for animation, transparency lost when converting to JPG — the page says so on the way in rather than leaving you to discover it afterwards.
Who this is for
Anyone with an image and a requirement attached to it. A photograph that has to be under 500 KB for a form that keeps rejecting it. A folder of product shots that all need the same width. A screenshot that needs to become a JPG because the software at the other end is twenty years old. A picture of something you are selling that should not carry the coordinates of your home.
It is particularly for people who should not be uploading their files at all: anyone handling medical images, legal exhibits, identity documents, client material under an agreement, or photographs of people who did not consent to a third party receiving them. For that work, “it is processed locally” is not a preference — it is the requirement.
The tools
Every tool has a dedicated page explaining what it does, how it does it, and what it cannot do:
Resize & crop
- Image resizer — Exact pixels, percentage or preset, with the aspect ratio locked by default.
- Image cropper — Drag-to-crop with ratio presets and exact numeric entry.
- Rotate & flip — Quarter-turn rotation and mirroring, applied to the actual pixels.
Compress
- Image compressor — Quality slider or target-KB search, with honest before/after byte counts.
Convert
- JPG to PNG — JPEG in, lossless PNG out — no upload, no signup.
- PNG to JPG — PNG to JPG with a quality slider and a background colour for transparency.
- JPG to WebP — JPEG to WebP with a live size comparison against the original.
- PNG to WebP — PNG to WebP in lossless or lossy mode, transparency kept.
- WebP to JPG — WebP to JPG for software that will not open WebP.
Privacy & metadata
- EXIF remover — Inspect GPS, camera and timestamp tags, then strip them losslessly.
Inspect
- Dimensions checker — Read dimensions, ratio, megapixels and the true format from the file bytes.
Batch
- Batch resizer — Resize a whole folder of images at once and download a ZIP.
- Batch compressor — Bulk compression with a per-file KB target and a ZIP download.
- Batch converter — Convert mixed formats to one target format, then download a ZIP.
What this is not
PixelEditor is not a photo editor. There are no filters, no retouching, no layers, no drawing tools and no AI features — no background removal, no upscaling, no generation. Those jobs want either a real editor or a server with a large model on it, and pretending otherwise would mean either doing them badly or sending your files away, which is the one thing this site exists to avoid.
It is also not a storage service. Nothing is kept, so nothing can be retrieved later. If you close the tab before downloading a result, the work is gone and has to be done again — a fair trade for a tool that never holds your files in the first place.
How it is paid for
A site made of static files that does no server-side work is inexpensive to run, which is what makes it possible to offer the tools free without advertising, without analytics, and without an upsell. There is no investor expecting your attention to be monetised, because there is nothing here that collects attention to sell.
If that ever changed, the honest thing would be to say so on this page and in the Privacy Policy rather than to let a flattering description stand after it stopped being true.
