About OptImg

OptImg is a free set of image tools that run entirely inside your web browser. It covers the everyday jobs people usually hand to an upload-based website: compressing photos, converting between formats, resizing, cropping and rotating, stripping camera and location data, removing backgrounds, enlarging small pictures, building favicons and app icons, turning images into a PDF, making and shrinking GIFs, tracing artwork into vector shapes, and generating QR codes.

There is no account to create, no queue to wait in, and no cap on how many files you process or how large they are. The practical limit is how much memory your own device can spare.

Most image websites work by sending your file to a server, processing it there, and sending the result back. That design has three costs you pay on every single file: the upload, the wait behind other people's jobs, and the fact that a copy of your image now sits on a computer you do not control.

OptImg removes all three. The page fetches its processing code once, then does the work locally. Your image is read straight from disk into your browser's memory and never travels anywhere. That matters most for exactly the files people hesitate to upload: passport and ID scans, medical images, signed contracts, screenshots of private conversations, photographs of children, and anything covered by a client confidentiality agreement.

It also means the tools keep working when your connection is slow or gone. Once a tool page has loaded, processing needs no network at all.

Skipping the round trip is not a rounding error. We measured OptImg against iLoveIMG, one of the most widely used upload-based image sites, on the same machine, the same connection, and the same input files, then published the full method, the per-run timings, and the cases where the gap is smallest.

We publish the losing and weak results too, along with the raw measurement files, so the numbers can be checked or repeated rather than taken on trust.

Some of these are decisions we could reverse tomorrow for short-term gain. Writing them down is how we make that harder, and how you can hold us to them.

• We don't upload, receive, or store your images. There is no server-side copy to leak, hand over, or forget to delete.
• We don't ask you to sign in. There are no user accounts.
• We don't build a profile of you. Site measurement is aggregate only: visit counts, page paths, countries, and whether a tool finished or failed.
• We don't add a paywall, a watermark, a daily limit, or a file-size tier to the output.

Because the work happens on your hardware, speed depends on your hardware. A recent laptop finishes a large conversion in a moment; an older phone will take noticeably longer on exactly the same file. Our published timings say which machine produced them for this reason.

A few operations are genuinely expensive. Producing AVIF from a very large photo, enlarging a picture with the AI upscaler, and removing a background all involve heavy computation, and each tool warns you before it starts. Very large files can also exhaust a mobile browser's memory — that is a limit of the device, not a policy of ours, and we would rather say so than pretend otherwise.

OptImg is developed and operated by Goyo Studio, an independent software studio. Product feedback, privacy questions, and business enquiries all reach a person at developer@goyostudio.io.

OptImg is free and intended to stay that way. It can afford to be: because there are no processing servers, the expensive part of the work happens on your device rather than ours, and what remains is the cost of serving a static site.

We plan to cover that with modest display advertising. Ads will sit apart from the tool controls, never between you and your result, and they are held to the same speed and completion-rate standards as the rest of the page. Where consent rules apply, advertising choices are collected through a Google-certified consent tool.
