About Helpful Guide

Helpful Guide is an independent website that publishes free, browser-based image utilities and written guides about working with images. It is operated by Hyper Scale Media LTDA, a Brazilian limited liability company registered under CNPJ 64.683.002/0001-05, with its principal place of business at Rua Edilson Araujo, 180, Sala J — Cara-Cara, Ponta Grossa - Paraná, CEP 84033-105, Brasil. The project is run by a small team of web developers who spent years re-compressing, resizing and converting images for client projects and grew tired of tools that demanded an account, watermarked the output or uploaded private files to a server.

What the site does

The site has two halves. The first is a set of practical tools: compressors, resizers, format converters, a cropper, inspection utilities and calculators. The second is a written archive explaining the concepts behind them, from how lossy compression discards information to how aspect ratio decides where a platform will crop your photo.

Both halves are meant to be genuinely useful on their own. The articles are not written to surround the tools with keywords; they exist because the questions they answer come up constantly.

How the tools work

Almost every tool here runs entirely inside your browser using the HTML canvas and file APIs. Your image is decoded in the page, processed in memory on your own device, and written back out as a new file. Nothing is transmitted, stored or logged.

The single exception is the website image extractor, which necessarily fetches a public page from our server in order to read its HTML. That request retrieves only the page you asked for, and the results are not retained after the response is returned.

Our editorial approach

Everything published here is written by people, reviewed before it goes live, and updated when the underlying facts change. We do not publish invented statistics, fabricated testimonials or review scores we did not measure. Where we give a number, such as typical WebP savings, it reflects widely reproduced results you can verify yourself with the tools on this site.

If you find something inaccurate or out of date, we would genuinely like to hear about it.

How the site is funded

Helpful Guide is free to use. Running costs are covered by advertising displayed alongside the content. Advertising is kept out of the working area of each tool: no interstitials, no countdown timers, no buttons designed to be mistaken for a download link.

We do not sell user data, because the tools do not collect image data in the first place.
