Merge PDFCombine up to 50 PDFs into one file in the order you choose. No account, nothing uploaded.
Compress PDFMake a PDF smaller by re-encoding the images inside it, dropping duplicated objects and clearing metadata, without sending the document anywhere.
PDF to WordTurn a PDF back into an editable DOCX, DOC, ODT or RTF file, with OCR for scans that have no text layer at all. Runs on our server; files are deleted automatically within about two hours.
JPG to PDFTurn a folder of JPG photos into one PDF, in the order you choose. A regular JPG goes in without re-compressing a single pixel.
Resize ImageChange the pixel dimensions of a photo by exact size, percentage or a ready preset, without leaving your browser.
Compress ImageShrink JPG, PNG, WebP, AVIF and GIF files in your browser: pick a level that keeps the resolution, or, for all but GIF, a target size in KB or MB.
HEIC to JPGTurn iPhone HEIC photos into JPG files that open everywhere, with the date and the GPS tag kept, and the picture the right way up.
WebP to JPGConvert WebP images to JPG in your browser, animated files included, with a background colour of your choice behind transparent areas.
Split PDFCut one PDF into several documents with scissors between pages, by page ranges, every N pages, or one page per file.
Remove BackgroundCut the subject out of any photo with AI: our server finds it in a reduced 1024 × 1024 copy, and your browser makes the cut-out from the photo itself. Download a transparent PNG, or the same cut-out on a solid colour.
Compress VideoMake a video file smaller in your browser. Pick a quality level or a target size in megabytes; nothing is uploaded anywhere.Word to PDFTurn a DOC or DOCX file into a PDF that keeps its layout, with fonts embedded so it renders the same on any device.

Your files stay yours
Most tools run in your browser using WebAssembly, so the file never leaves your device. The few that need a server delete your file within about two hours.
No account, no waiting
Open a tool and use it. There is no sign-up, no email confirmation and no captcha between you and the result.
No subscription, ever
Every tool is free: no paid tier, no quota on browser tools, nothing locked behind a plan. Advertising pays for the servers and the work behind it. The few server tools accept up to 30 jobs an hour so they stay free for everyone.
How it works
- 1
Pick your tool
Search for what you need, browse by category, or drop a file and let us suggest the format.
- 2
Drop your files
Drag and drop or choose a file. With browser tools it loads straight from your device; a tool that needs the server says so on its page.
- 3
Download the result
Browser tools finish on your device; the few server tools send the result back to this page. Download the file, or send it straight into the next tool.
One file, several tools — without re-uploading
Every result ends with a “What's next?” list: merge PDFs, then compress the result, then protect it with a password — the file passes from tool to tool inside your browser, with no download and upload in between. Chains you repeat can be kept on the Saved chains page.
Frequently asked questions
How does browser-based processing work?
In browser tools, the processing libraries are compiled to WebAssembly and run inside your browser tab. The page reads the file from disk itself and never sends it anywhere.
Is there a file size limit?
Only a technical one. Browser tools work inside your device's memory, so each tool has its own limit, from 5 MB for text files to 300 MB for most PDF tools; every tool page states it. Server-side conversions — PDF to Word, OCR and other Office formats — take files up to 300 MB and are capped at 30 jobs per hour per person, so that one user cannot block the queue for everyone.
Is there a limit on the number of files or tasks?
No. There is no daily counter and no paid tier above the free one: process as many files as you like. The only cap is on server-side conversions, and it is stated on those pages.
Do I need an account or a subscription?
No. PulsarKit has no signup, no email confirmation, no captcha and no payment form. Advertising on the site pays for the servers, so nothing is locked behind a plan.
Can I run several tools on one file?
Yes. Every result ends with a “What's next?” list: merge PDFs, then compress the result, then protect it with a password — the file passes from tool to tool inside your browser, with no download and upload in between. Chains you repeat can be kept on the Saved chains page.
Why is everything free?
Advertising pays for the site, and that is what keeps every tool free. There are no paid tiers, no paywalls and no accounts.
Are my files private?
In browser tools, yes: the file is processed locally and discarded when you close the tab, so we cannot see it. The few server tools, such as OCR and Word or Excel conversion, send the file over an encrypted connection and delete it within about two hours. Each tool page says which kind it is.
Which browsers are supported?
Chrome 90+, Firefox 88+, Safari 15+ and Edge 90+, on desktop and mobile alike.
