To speed things up, put the page name and issue type in the subject line, for example "[Bug] image compression - WebP download fails".
How we handle common requests
- Bug reports: include the page URL, browser and version, and the steps to reproduce. Describe file type and size instead of sending sensitive files.
- Feature requests: describe your use case and the result you expect; we assess priority from there.
- Content corrections: point out the page and the mistake, ideally with a source.
- Advertising and partnerships: mention your company or product and the proposed format.
- Copyright complaints: identify the exact page and the rights involved; we act promptly.
- Something broken (blank page, dead button, obviously wrong result): refresh or try another browser first, then describe what you saw, so we can tell a one-off glitch from a reproducible bug.
A note on privacy
No personal details are required to use any tool here. Please do not email ID cards, bank details or other sensitive data, and mask screenshots first if you must send one — our image mosaic tool runs locally and can help.
Advertising and partnerships
- We accept ads and sponsorships relevant to the tools’ use cases, as long as they never interrupt: no pop-ups, no covering content, no auto-playing sound.
- We turn down gambling, exaggerated medical claims and other high-risk or misleading campaigns.
If you would like to advertise, browse the tool categories and page structure first, then tell us the position and format you have in mind — we will give you a clear yes or no.
Out of scope
We do not do homework, essays, software cracking or account recovery; messages containing illegal content, personal attacks or obvious bulk spam will not receive a reply.
How to write an effective report
- Name the page or paste the full URL, e.g. "image compression page".
- Mention your device and browser, e.g. iPhone 15 / Safari 17 or Windows 11 / Chrome 130.
- Describe what you expected and what actually happened, and where they differ.
- For calculation issues, include the numbers you entered and the result you got.
That is enough for us to locate almost any issue in one pass, saving a round of back-and-forth — and your time.
What happens next
- Received: your email enters a queue ordered by impact.
- Reproduced: we recreate the issue to see whether it is a bug or a usage difference.
- Fixed or scheduled: quick fixes ship in the next release, larger items are planned and appear in the changelog.
- Replied: whatever the outcome, we tell you what we decided.
Other notes
- We do not offer phone or live chat support; email is the only channel.
- The footer navigation on every page links to our privacy policy and terms of service; for how data is handled, see the privacy policy first.

FAQ
How soon will you reply?
Usually within 1-3 business days. Bug reports with clear reproduction steps are handled first.
May I send a sample file with my report?
Prefer describing the file instead. If a screenshot is essential, please mask sensitive parts first — the image mosaic tool on this site does that locally.
