FileVert's answer:
FileVert Image Compressor processes everything directly in your browser. No file is ever uploaded to a server, no account is required, and there is no usage limit. It supports all major formats — JPG, PNG, WebP, BMP, GIF and TIFF — with batch processing and image resizing built in. It is the only image compressor that combines true local processing, unlimited batch compression, and full GDPR compliance in a single free tool.
FileVert's answer:
Most online image compressors upload your files to their servers, impose limits on file count or size, or require a paid plan for batch processing. FileVert Image Compressor does none of that. It is entirely free, processes files locally in your browser, supports batch compression across all major formats, and requires zero sign-up. For users who handle sensitive images or simply want a fast, private, unlimited tool, it is the obvious choice over TinyPNG, Compressor.io or iLoveIMG.
FileVert's answer:
Web developers and frontend engineers optimizing assets for production, graphic designers preparing images for delivery, marketing and content teams managing large sets of visuals, and privacy-conscious users who do not want their files sent to third-party servers. It is also widely used by European companies and agencies that must comply with GDPR.
FileVert's answer:
FileVert was originally built as an internal tool at FileVert to handle image optimization without relying on third-party services. After using it daily for months, the team decided to make it publicly available for free. The core philosophy — keep files local, respect privacy, remove friction has stayed the same since day one.
FileVert's answer:
The tool is built entirely with web technologies running client-side: JavaScript, WebAssembly, and the browser's native Canvas and File APIs. Compression codecs for WebP and AVIF are handled via WebAssembly libraries, enabling near-native performance directly in the browser without any server-side processing.
FileVert's answer:
No enterprise customer list — the tool is free and open to all users without registration
The only negative thing about this web app, is that it's not clear which formats are supported in which browsers.

It often comes down to compat, and developer requests. Personally I find in-browser encoding for images inadequate, because it doesn't expose enough options. When we built https://squoosh.app/, we exposed the browser encoders for completeness, but they're pretty bad compared to the wasm codecs. - Source: Hacker News / 8 days ago
Its a fun challenge. I used https://squoosh.app to make a pretty good one. Mostly just a resize and then OxiPNG for compression. Managed a 124x62 black/white image. OP has a resolution of 195x53, so I had very similar, but slightly worse I think? Mostly a different aspect ratio + map projection I think. Playing with Squoosh.app is very fun, and you can very easily see how the jump from 500b to ~1.5kb turns a map... - Source: Hacker News / 2 months ago
Use a free tool like Squoosh (by Google) to batch convert your existing images to WebP. - Source: dev.to / 3 months ago
Every image goes through Squoosh before it lands in any repo I own. Drag the file in, pick WebP or AVIF, drag the quality slider until the preview still looks clean, download. The size reduction is usually 60–80% with no visible quality loss. It runs entirely locally in your browser — nothing is uploaded anywhere. For a performance-conscious developer this matters. Best for: Pre-commit image optimisation, blog... - Source: dev.to / 5 months ago
The Squoosh image compression app from Google is a great example. It runs codecs like MozJPEG and WebP entirely in WASM, processing large image buffers with minimal boundary crossings. Near-native compression performance, right in the browser. - Source: dev.to / 5 months ago
