Base97

What is base97?

base97 is a free, no-sign-up collection of focused browser-based file tools for everyday image, document and audio tasks. Instead of a bloated all-in-one suite, it organizes small, single-purpose utilities into three clear toolboxes so you can go from "I need to…" to "all done" in a few steps.

Toolboxes

• Image Tools — Compress, resize and convert images, plus specialized helpers such as passport photo creation. Tagline: "A little less size. All the detail."
• PDF Tools — Convert TXT, RTF, Markdown, CSV, HTML, Excel, PowerPoint, Word and Apple Pages files into PDF, with planned workflows for web content, data, ebooks and iWork formats.
• Audio Tools — Cut, combine, convert and record everyday audio.

Popular tools

Image Compressor, Image Resizer, Crop / Rotate / Flip / Blur / Watermark Image, HEIC to JPG, WebP to JPG, PNG to JPG, JPG to PNG, AVIF to JPG, Compress Image to 100 KB, Image to PDF, and a full set of document-to-PDF converters (TXT, RTF, Markdown, CSV, HTML, Excel, PPT, Word, Pages).

Key features

• No account required — open a tool and start working immediately.
• Browser-based processing where possible — less uploading and less waiting for supported tasks.
• Transparent processing details — each tool documents whether work happens locally in the browser or on a server, so you can judge what is safe to upload.
• Fast discovery — category filters (Images, Documents, Audio, Utilities), a task-oriented search box ("What would you like to do?") and a ⌘K quick-find command palette.
• Cross-device — usable on desktop, tablet and phone, with per-tool file-size limits noted.

Who it's for

Casual and professional users who need a quick, one-off file fix: shrinking a photo before emailing it, resizing an image for a specific frame, turning a spreadsheet or slide deck into a shareable PDF, or trimming a short audio clip — without installing software or creating an account.

Unique selling points

A deliberately minimal, design-led interface ("Small tools. Big possibilities."), a privacy-first stance with clear file-handling notes, and a curated rather than overwhelming catalog of tools.
