Resize before compressing
A small card rarely needs a camera’s full-resolution file. Generate dimensions suited to likely layouts.
- — Set explicit dimensions
- — Use responsive variants
- — Preserve important detail

Understand the result before acting
Choose a suitable format
WebP works broadly; AVIF can be smaller where supported. PNG remains useful for particular transparency or lossless needs.
- — Compare visually
- — Keep an original source
- — Use descriptive alt text
How the result is produced
All processing happens within the current browser tab. The tool uses browser APIs to generate, inspect or transform the supplied material and does not submit the sensitive value to an AHANIX endpoint. Closing or clearing the workspace removes the in-memory result.
- — Inputs are shown before action
- — No unavailable result is invented
- — The output remains reviewable
What the result means — and does not mean
The result is a practical starting point, not a clearance, professional opinion or guaranteed outcome. Check the output against the actual business, platform rules and intended audience before publishing or relying on it.
- — Treat warnings as prompts for investigation
- — Confirm important changes manually
- — Keep the stated limitation with the result
Common mistakes to avoid
A generated output becomes risky when it is copied without review, applied to the wrong page or treated as permanent. Another common mistake is optimising a single measurable signal while ignoring the visitor’s task. Keep a copy of existing technical configuration before replacing it and test the resulting customer journey after implementation.
- — Do not chase a score without context
- — Do not publish a draft unchanged
- — Do not replace working configuration without a backup
Privacy and responsible use
Image binary data stays in the browser and is not uploaded, logged or sent to analytics. Review the visible image before download because local compression can still remove quality or metadata you intended to retain.
- — Provide only necessary information
- — Review the AHANIX Privacy Policy
- — Clear sensitive local inputs when finished
What to do next
Start with the highest-impact finding or the option that most closely fits the real page. Record the original state, make one controlled change and verify the result on mobile and desktop. Where a decision involves legal obligations, security configuration, production access or significant commercial cost, obtain an appropriate manual review.
- — Prioritise customer impact
- — Test after implementation
- — Escalate decisions that require professional judgement
Questions about Image Optimiser
Are images uploaded?
No. This optimiser uses the browser canvas.
Is the smallest file always best?
No. Excessive compression can harm clarity and credibility.
Is the result guaranteed?
No. It is a practical automated result or drafting aid with the limitations explained on the page.
Do I have to request an email report?
No. The basic result is available on the page without marketing consent. Eligible tools offer an optional report.
What should I do before publishing the result?
Review it against the real website, business activity and current platform or legal requirements, then test any implementation.
