Overall verdict

  • I don't have verified, up-to-date information about PixKeep.app specifically, so I can't confirm its quality, safety, or reliability. Before using it, research its reputation, check reviews, verify how it handles your data/privacy, and test with non-sensitive files first.

Questions & Answers

As answered by people managing PixKeep.app and Renderthis.

What makes your product unique?

PixKeep.app's answer

All image processing happens 100% in your browser — files never leave your device, and every tool works offline once loaded. PixKeep also has a built-in visual comparison tool: split / side-by-side / diff views with a pixel-level diff heatmap and a DSSIM score, so you can see exactly what compression or conversion changed before you save.

Why should a person choose your product over its competitors?

PixKeep.app's answer

  • No uploads: conversion happens on your device — no queue, no server-imposed file caps, no privacy risk
  • No account, no sign-up, no watermark — 100% free
  • Works offline once loaded (PWA)
  • Visual quality check: split / side-by-side / diff comparison with DSSIM score before saving
  • Beyond conversion: compress, resize, crop, rotate, flip, compare — plus ready-made scenes and a passport photo maker with 300 DPI print sheets

How would you describe the primary audience of your product?

PixKeep.app's answer

iPhone users converting HEIC photos to universal formats, visa and passport applicants preparing compliant photos, social media creators sizing images for Instagram/YouTube/LinkedIn/Discord, and privacy-conscious users who don't want their photos on someone else's server.

What's the story behind your product?

PixKeep.app's answer

PixKeep started as a side project by a developer with 10+ years image/video processing experience. The motivation: popular image converters upload your photos to a server, add queues, watermarks and file limits — while modern browsers can do all of it locally. PixKeep proves a browser-only toolkit can be faster, free, and private by default, with zero server costs keeping it sustainable as a free product.

Which are the primary technologies used for building your product?

PixKeep.app's answer

  • Astro (static site generation) + TypeScript
  • Browser Canvas API and WebCodecs
  • WASM codecs: MozJPEG, WebP, AVIF, OxiPNG
  • heic2any (HEIC), UTIF.js (TIFF), pdf.js + jsPDF (PDF), gif.js (GIF), Cropper.js
  • Service Worker (offline PWA)
  • Hosted on Cloudflare Pages

Who are some of the biggest customers of your product?

PixKeep.app's answer

  • PixKeep is free and account-free — we don't track users by design
  • Typical users: iPhone owners converting HEIC photos, passport/visa applicants, social media creators, and anyone who prefers not to upload personal photos to a server
