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 FullStackToolkit and PixKeep.app.

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
