Free AI tools for images, PDFs, video & résumés — plus developer mock interviews
Browser-native pipelines for creatives, builders, recruiters, and students—paired with one AI interview cockpit above this fold.
Full platform overview (SEO + readers)
Merge AI combines free browser-based utilities with an AI mock interview workspace built for developers and serious job seekers. Use it to compress, convert, resize, and clean up images; merge, split, compress, rotate, or convert PDFs; trim GIF and MP4 workflows; trim, join, split, compress, and convert audio locally; remove audio from video, swap backgrounds where supported, and prep clips for messaging apps. Résumé tools help with ATS readability, wording suggestions, layouts, and builder flows.
The interview shell above lets you practise technical conversations out loud—with pacing and follow-ups closer to real hiring loops—without installing desktop suites or juggling half a dozen ad-heavy single-purpose sites. Everything shares one calm design language: predictable upload → adjust → export patterns, and fast feedback in modern browsers. Start your interview rehearsal at the top of this page, or open any category below when you need a concrete file task done before you ship.
Image tools
Compress, convert, crop, OCR, upscale, strip backgrounds, and ship social-ready assets—without juggling random converter tabs.
Scroll sideways · every tile is crawlable HTML
PDF tools
Assemble onboarding packs, carve exhibits, lighten files for email, and bounce between Word-ready flows when reviewers change specs.
Video tools
Compress for Slack & email, shuttle between GIF ⇄ MP4, strip audio from captures, or grab stills—the stuff that shouldn’t require Premiere.

Audio tools
Cut dead air, stitch takes, split long recordings, shave bitrate for email, bounce formats, or even out loudness—FFmpeg WASM stays in the tab.
Developer tools
Pretty JSON before you paste into tickets, sling Base64, reshape CSV-ish exports, and vet Unix timestamps straight from Merge AI in the browser.

Résumé tools
Stress-check ATS parsing, tighten bullet copy, scaffold polished PDF shells, then iterate layouts before firing applications.

Why operators pick Merge AI
Free core tools
Bread-and-butter compress and convert workflows stay approachable before you graduate to quotas.
No signup for most utilities
Drop a file when you simply need throughput—authentication only where sessions matter.
Predictable pipelines
Every surface follows upload → tweak → download so muscle memory survives context switches.
Security-conscious defaults
We bias toward browser execution when feasible—pair that with sensible org hygiene on PHI/PII.
Interviews beside tooling
Rehearse out loud atop the exact stack that polishes screenshots and PDF collateral.
