About Free Image Lab

What’s different

Most free image tools are worse than they need to be. You arrive from a search, and before you can do the single thing you came for you are asked to sign up, wait for an upload, watch a progress bar that is really an advert, and then discover the download is watermarked or capped unless you pay.

None of that is necessary. Cropping an image, changing its format, or making it smaller are things a browser has been able to do on its own for years. So that is how these are built: the work happens on your device, the moment you drop a file in.

The less obvious difference is what happens to your picture in the process. A lot of tools take a shortcut that costs you quality without ever mentioning it — the easy implementation, not the right one. Most of the work here went into not taking those shortcuts.

Built to preserve quality

These are the specific decisions, tool by tool. They are the difference between a file that survives the round trip and one that comes back slightly worse than it went in.

Cropping never resamples

The selected area is copied straight out of the original at its native resolution — the pixels that come out are the pixels that went in, not a scaled approximation of them. The selection is also tracked in image coordinates rather than screen coordinates, so the result is identical whether the preview happens to be rendered at 300 pixels wide or 900.

Resizing keeps your format, and uses a proper scaler

Resize a JPG here and you get a JPG back. A lot of tools hand you a PNG several times larger because that was easier to implement — a file that is technically lossless and practically useless.

Browsers also default to a cheap scaling algorithm that aliases badly when shrinking a photo, producing the jagged edges you sometimes see from free resizers. High-quality smoothing is turned on explicitly here.

PNG compression that actually compresses

This is the clearest example of the shortcut problem. PNG is a lossless format and the browser’s encoder ignores any quality setting you give it — so a PNG compressor built the obvious way hands back a file the same size while appearing to work.

What genuinely shrinks a PNG is reducing how many distinct colors it contains, because that is what its compression exploits. So this tool does the real thing: median-cut color quantization, with optional Floyd–Steinberg dithering to keep gradients smooth instead of banded. On a photograph that is typically a 50–60% saving; on a flat logo it can be far more with no visible change at all.

Removing metadata does not touch the picture

The common implementation strips EXIF by re-saving the photo through a canvas, which does remove the data — and silently recompresses your image every time. A privacy tool that quietly degrades the thing it is protecting.

Here the file container is edited directly: the metadata segments are removed and the compressed image data is copied across byte for byte, never decoded. The picture that comes out is bit-for-bit identical to the one that went in.

PDFs embed your JPGs untouched

A JPG is already compressed in a form the PDF format understands natively. So when you build a PDF here, JPG pages are written into the file exactly as they arrived — not decoded, not re-encoded, not rasterized. Most image-to-PDF tools push everything through a canvas and recompress it, losing a little on every page.

Conversions tell you what you are trading

Every converter shows the before and after file size and the exact percentage difference, so you can judge the trade rather than guess at it. PNG to JPG lets you choose what color fills transparent areas — most tools default to black without asking, which is almost never what anyone wants. SVG to PNG reads the vector’s own viewBox instead of letting the browser guess a size, which is why it does not produce the mysteriously blank or wrongly-sized exports other converters do.

Compressors admit when they cannot help

If a compressed result comes out larger than the original, that means your file was already compressed harder than the setting you chose. The tool says so rather than letting you download something worse than what you started with.

Everything runs in your browser

There is no upload. When you drop an image here it is read by your own browser and processed there — it is never transmitted to us, because there is nowhere to transmit it to. Every page on this site is a static file, and all the actual work is code running on your machine.

You do not have to take that on faith. Open your browser’s developer tools, switch to the Network tab, and use any tool on the site. You will not see your image go anywhere.

It matters most where it obviously matters. The EXIF viewer shows the GPS coordinates hidden inside your photos, and the metadata remover strips them. Handing a photo to a stranger’s server to find out whether it reveals your home address would rather defeat the purpose.

It is also why there are no file size caps, no queues, and no waiting. There is no server to be busy.

Why it’s free

Advertising, and nothing else. No premium tier, no data being sold, and no account needed to use anything.

Because the tools run on your device, this site costs very little to operate however many people use it — which is precisely why it can stay free without needing to extract something from you. Adverts are placed where they cannot be mistaken for a download or upload button, and never between you and the thing you came to do.

We plan to add an optional account for a points leaderboard, because it is a bit of fun. Using the tools will never require one.

Who runs it

Free Image Lab is an independent project by Eric Daft of Boundliss Media. It is not a venture-backed startup with a growth target, and there is no plan to bolt on a subscription later — it exists because these tools should have been free and unannoying all along.
