I built LightPIX — a free image compressor that respects you (no signup, no watermark, keeps your format)
Hey IH 👋
I've been quietly building LightPIX, a free online image compressor, and it's time to share it and ask for honest feedback.

What it does: compress PNG, JPEG & WebP up to ~80% smaller in the browser — no signup, no watermark, no upload limits, and images are deleted right after processing (never stored).
Why I built it: most free compressors make you sign up, slap on a watermark, silently turn your PNG into a WebP, or cap you at a handful of files. I wanted one that just… respects you:
Keeps your format by default (a PNG comes back a PNG) — but you can opt in to WebP/AVIF for max savings.
Compress to a target size ("get this under 100 KB") — perfect for email/upload limits.
Optional resize for the web, batch up to 20 at once, ZIP download.
There's also a free WordPress plugin that auto-compresses on upload.
Traction: it's live and getting used — a few hundred images compressed, ~0.5 GB saved so far. Modest but real. Now I'm focused on distribution + making it genuinely more useful.
I'd love feedback on:
Is the compress → download flow clear?
What one feature would make you switch from TinyPNG/Squoosh?
Anything that feels off or missing?
Happy to talk stack too (Next.js + sharp on Cloud Run, static SEO pages). Thanks for reading 🙏
The few hundred real compressions are a more useful signal than the feature list.
Curious whether users are choosing LightPIX mainly for the no-signup/privacy angle, or because the target-size workflow solves something TinyPNG/Squoosh don't.
Yeah, that matches what I'm seeing. Privacy is the "why I clicked," target-size is the "why I stayed."
The interesting bit: target-size is a workflow problem, not a compression problem. People aren't chasing "smaller" — they're trying to hit a hard constraint (a 100 KB upload cap, a 5 MB email limit) without the trial-and-error of nudging a quality slider and re-exporting. That manual loop is exactly what TinyPNG/Squoosh leave you doing.
So I'm leaning into it — presets for the constraints people actually hit (upload fields, avatar sizes, email limits), and maybe a "fit to X" that also auto-picks the format.
Thanks for pushing on it. Would per-image targets (different sizes in one batch) matter to you, or is one target per batch enough?
I’d be interested in continuing the conversation privately rather than going deeper here. What’s the best email to reach you on?
