Friendly file tools that never upload a thing.
Pick a tool, drop in your file or paste your text, and you're done. It all happens right here in your browser, so your stuff stays yours.
Bank statements → QuickBooks. Nothing uploaded.
The one file people rightly refuse to upload, handled the FileKiln way: drop a statement PDF, review every parsed transaction, and download a QuickBooks-ready .qbo - or QFX, OFX, CSV, Excel. The bank data never leaves your tab.

Big files? No problem.
Real engines that run in your browser. Files this big usually get uploaded somewhere. Not here.

One short email when something new is out. Every email has an unsubscribe link.
Why it feels safe here
Config files carry secrets and exports carry customer data. Most “free online converters” quietly ship both to a server. FileKiln has no upload endpoint to trust, because there is no upload.
No upload button
There's nowhere for your file to go. Each tool is a plain page that does the work in your browser.
Real, careful tools
Proper parsers under the hood. If something's off, we point to the exact line, kindly.
Works on a plane
Open the page once, then go offline. Everything keeps working.
Tools by task
Every tool has its own page with step-by-step instructions, a worked example, and fixes for the problems people run into most.
Bank statements and accounting
Turn a statement PDF into a QuickBooks .qbo file or a CSV or Excel sheet, pull tables out of any PDF into CSV, or open a QBO, OFX or QIF export as a spreadsheet.
Email, contacts and calendars
Read Outlook .msg files and .mbox mail archives without a mail program, convert vCard contacts to CSV, and list every event in an .ics calendar file.
Images, 3D models and audio
Flatten a Photoshop PSD to PNG, slice an STL model into G-code for a 3D printer, and transcribe an MP3 into MIDI notes.
Config and data formats
Convert YAML to JSON and back, CSV to JSON and JSON to CSV, and format or validate JSON.
Encoding and security
Encode and decode Base64, URLs and HTML entities, inspect a JWT, hash text with SHA-256, and make passwords and UUIDs.
Developer utilities
Test a regular expression, explain a cron schedule, convert Unix timestamps, number bases and HEX and RGB colors, and strip hidden metadata from PDF and Word files.
Writing and text
Count words and reading time, compare two texts, change case, remove duplicate lines, make URL slugs, convert Markdown to HTML, and generate placeholder text.
Marketing
Check whether an A/B test result is significant, build UTM-tagged campaign links, and preview how a page will look when shared with Open Graph tags.
