About Image-Compressor.uk

Image-Compressor.uk is an independent, browser-based image optimisation toolkit built and edited by Jamie Pow, a UK-based technical product operator with a decade of experience shipping web software. The site launched in 2025 out of frustration with the shape of the existing image-tool market: aggressive paywalls, hidden upload pipelines, dark-pattern quality reductions on the free tier, and a lack of clear technical explanation about what the tool is actually doing to your file.

Every tool on this site runs entirely in your browser using the Canvas API — your source images are never uploaded to any server we control. That is not a marketing claim; it is a technical consequence of how the tools are architected (there is no upload endpoint). You can verify this by opening the browser DevTools → Network tab and confirming zero outbound requests carrying your image data.

Who runs the site

Jamie Pow is the founder, sole editor and sole developer. Ten years of technical product work across e-commerce, media and B2B SaaS, including team leadership at UK product organisations that ship performance-sensitive web applications at scale. That background informs everything on the site: the technical claims we make about compression quality, the specific byte and dimension targets our presets ship, and the editorial decisions about which tools are worth building and which are not.

All editorial content on this site is written or reviewed by Jamie personally. There are no ghost-written articles, no syndicated content and no AI-generated body copy. Where AI assistance is used at all it is limited to editorial suggestions on already-drafted content, and every published sentence is reviewed by a human.

Editorial standards

Every technical claim on this site is either (a) directly verifiable in the browser (compression ratios, dimensions, file formats), (b) sourced from primary documentation (WHATWG, W3C, RFCs, Google Web.dev), or (c) grounded in real production experience. Where we cite a specific behaviour of a third-party platform (e.g. "Gmail caps attachments at 25 MB", "Instagram re-encodes uploads at 1080 px wide"), we reference the current platform documentation or measured behaviour as of the date shown on the page.

Format guides and comparison articles are dated with a "last reviewed" timestamp. If you spot something out of date or wrong, please email — corrections are welcomed and typically shipped the same day.

The tools we ship

Core image tools, all free, all browser-based:

• Compress — quality slider + dimension cap + live before/after preview
• Resize — exact pixels, percentages, or social media presets
• Convert — JPG, PNG, WebP and AVIF
• Crop — aspect-ratio presets, draggable bounds
• Bulk compress — process a folder, download as one ZIP
• Metadata viewer and EXIF stripper
• Favicon, Open Graph and X card generators

Deep-reference material: the image size guide (per-platform dimensions) and image format guide (JPEG vs PNG vs WebP vs AVIF vs HEIC vs SVG).

Why browser-based matters

The Canvas API in every modern browser can decode, re-encode, resize and re-quantise images entirely on the client. That means the tools can be free (no server cost), fast (no round-trip latency), and private (your file never leaves your device). It also means the tools have an upper ceiling — very large batches benefit from a proper build-time image pipeline, and we're honest about that in the docs where relevant.

For readers processing sensitive material (client work under NDA, identity documents, unpublished designs, contracts), the zero-upload guarantee is more than a nice-to-have. Nothing you drop into the compressor touches infrastructure we (or anyone else) control.

How the site is funded

Display advertising via Google AdSense pays for the site's hosting, domain, and the time it takes to maintain and expand the toolkit. Ad placement is deliberately conservative: nothing inside the tool UI, nothing that obscures content, no interstitials, no autoplay video, no pop-ups. Full detail is in the privacy policy.

A small number of tool pages carry affiliate recommendations for approved partners (currently ParentShield and Crazy Egg). Every affiliate link is marked with a disclosure inline next to the CTA and carries a link to the full affiliate disclosure. Editorial decisions are never influenced by commercial relationships; if we ever mention a partner unfavourably, we will. The full policy is in the affiliate disclosure page.
