Free Online File Tools — Compress, Convert & Merge Without Uploading
Shrink your files. Not your privacy.
OnlyFiles helps you shrink, compress, convert, merge, encrypt, watermark and scrub your files entirely on your own device, protecting your privacy. No server round-trip, ever — which means no upload cap, no "processing" spinner while a stranger's server holds your photos, and nothing to leak in a breach that never happens.
OnlyFiles vs iLovePDF, Smallpdf & TinyPNG — Why Files Stay on Your Device
Most free converters are a single tool that quietly uploads your file to make money on ads or "premium" upsells. OnlyFiles bundles the tools people usually have to hunt across five different sketchy sites for — and none of them ever leave your browser.
| Capability | Typical free converter site | OnlyFiles |
|---|---|---|
| Compress & convert images / PDFs / video | Usually, via upload | ✓ On-device |
| Strips GPS & camera metadata from photos before you share them | Rare — and they saw it first | ✓ Never leaves your device |
| Password-protect a file with real AES-256 encryption | Almost never offered | ✓ Built in |
| Merge, split, rotate & watermark PDFs | Behind a paywall + upload | ✓ Included |
| Batch-process many files at once | Paid tier, still uploaded | ✓ Included |
| Works with your Wi-Fi off | Never | ✓ Yes |
Compress, Convert & Merge Files Without Uploading
Unlike iLovePDF or Smallpdf, your files never leave your device. Everything processes locally in your browser.
1. Drop Your File
Drag and drop any PDF, image, or video into the tool. No signup, no account, no email required.
2. Processed On Your Device
Your browser's built-in WebAssembly, Canvas, and Web Crypto APIs handle the work. Zero bytes are uploaded to any server.
3. Download the Result
Your compressed, converted, or encrypted file downloads instantly from browser memory. No waiting, no queue.
Image Compression & Conversion Tools
Compress, watermark, scrub and package images — every pixel processed by your own browser's canvas.
Showing a generated sample image — drop your own file above to try it for real.
Choose files to begin — each one is compressed independently and appears below with its own download button.
Drop a photo above, tune the watermark, then download.
PDF Compression & Editing Tools
Compress, merge and edit PDFs without a single byte touching a server.
Recompresses every embedded photo inside the PDF, not just metadata — that's what actually shrinks scans and image-heavy files. Pure text PDFs were already small and see smaller gains.
Add two or more PDFs, use the arrows to set their order, then merge.
Drop a PDF above, then set which pages to keep, rotation and an optional watermark.
Add one or more images, use the arrows to set their order, then combine — one image per page.
Video Compression & Editing Tools
Compress, trim, grab frames and pull audio — all re-encoded live in your browser.
Processing plays through your clip once, fully on-device. Output is .webm.
Drop a video, set your start/end points, then export. Output is .webm.
Each grabbed frame gets its own thumbnail and download button below.
File Encryption & Security Tools
Real AES-256 encryption, generated and decrypted entirely in your browser. OnlyFiles never sees your password or your file.
Password strength appears here.
If you lose this password, the file cannot be recovered — OnlyFiles stores nothing, anywhere.
Drop the encrypted file and enter its password to recover the original.
Utility Tools — QR Codes & Batch Renaming
The small tools that don't deserve their own five ad-covered websites.
Regenerates live as you type. A logo forces error-correction to H automatically.
Add files above, adjust the pattern, then download each renamed file individually below.
Photo Effects, Blur & Image Enhancement
Color filters, creative effects, blur/redaction, and image upscaling — all rendered by your own browser, nothing sent anywhere.
Drop a photo above, pick a filter, then fine-tune with the sliders.
Drop a photo above. With "Drag a region" selected, click and drag on the preview to choose the area.
Drop a photo above — this sharpens detail while enlarging, it isn't a neural super-resolution model, so extreme blow-ups will still look soft.

Questions people actually ask
Do my files ever get uploaded anywhere?+
No. Every tool runs with your browser's own decoding, canvas, crypto and recording APIs. There's no server call in the processing path — you can disconnect your Wi-Fi after the page loads and every tool still works.
Are all 19 tools really free?+
Yes. Every single tool — including batch processing, watermarking, the privacy scrubber, favicon generator, PDF merge and page editing, video trim & frame grabber, AES-256 encryption, QR codes, bulk renamer, blur redaction, and the image upscaler — is currently 100% free with no paywalls or card required.
Do I need to pay or enter a credit card?+
No. You can use all 19 tools right now with no account, no payment, and no credit card required.
How does the metadata scrubber actually work?+
Photos from phones and cameras often embed EXIF data — GPS coordinates, camera model, timestamp, sometimes even the software used to edit them. The Privacy Scrubber reads that block directly from the file's bytes, shows you exactly what's in it, then removes it either losslessly (cutting just the metadata segment, so image quality is untouched) or by re-encoding the pixels fresh. All of this happens locally; the file is never sent anywhere to be inspected.
Is the encryption actually secure?+
The Security Vault uses AES-256-GCM with a key derived from your password via PBKDF2 (250,000 iterations, SHA-256) — all through your browser's native Web Crypto API, the same primitives used by password managers. Your password and the original file never leave your device, and OnlyFiles has no way to recover a lost password.
Do I need to create an account or subscribe?+
No. You do not need to create an account, log in, or pay for a subscription. Every single tool on OnlyFiles is 100% free and runs directly in your browser without any registration.
Does it work on my phone?+
Yes — it's a website, not an app, so it runs in any modern mobile or desktop browser without an install. Some heavier tools (video processing) are faster on desktop.
