benchzy the file workshop

File tools that run in your browser · Nothing is uploaded

File jobs, done on your device.

Benchzy is a workshop of file tools that run inside your web browser. Your files are processed on your own device and are never uploaded. No accounts, no daily counters, no watermarks. No tricks at the download button.

In a hurry? Shrink a photo for a form → exact KB, about a minute

Background removal
Remove background ReadyOpen → Full size cutouts. The program runs in your browser; the first run loads it (44.3 MB in 11 checked pieces, printed before it loads). Batch remove background ReadyOpen → A whole folder of photos cut out in one run, one program load for the batch, one ZIP of full-size PNGs out. Free background remover, full resolution ReadyOpen → The full-size promise in plain words, with the dated facts about the famous alternative that closes 1 December.
PDF jobs
Compress PDF to a size ReadyOpen → Pick a target, 200 KB, 500 KB, 2 MB or your own number, and the page works to land under it. Compress PDF to 200 KB ReadyOpen → The tight-portal preset: the same tool, with the 200 KB target already set. Compress PDF to 50 KB ReadyOpen → The visa-portal preset: the same tool, with the 50 KB target already set. Compress PDF to 100 KB ReadyOpen → The form-portal preset: the same tool, with the 100 KB target already set. Compress PDF to 500 KB ReadyOpen → The email-and-boards preset: the same tool, with the 500 KB target already set. Compress PDF to 1 MB ReadyOpen → The attachment preset: the same tool, with the 1 MB target already set. Compress PDF, strong ReadyOpen → No target: the deep end of the shrink ladder, smallest honest result, the photo trade printed on the result. Merge PDF ReadyOpen → As many files as your device can hold, in your order. In our tests, merging 25 files took 71 milliseconds. Interleave PDF ReadyOpen → Deal two PDFs together a page at a time, A1 B1 A2 B2: the duplex scan repair, with a back-to-front option for the second file. Split PDF ReadyOpen → Pull out a page range as one file, take every page as its own PDF, or cut parts under a size you set. Remove and organise pages ReadyOpen → See every page, take pages out, drag the rest into order, copy a page. Pages move inside the file; nothing is rebuilt. Sign PDF ReadyOpen → Your own signature on your own document, drawn into the page. Plainly scoped: no requests to others, no certificates. Flatten PDF ReadyOpen → Bake a filled form's answers into the pages, so the file displays and prints the same everywhere. Protect PDF ReadyOpen → Put a real password on your own PDF, AES-256, without the file or the password leaving this page. Unlock PDF ReadyOpen → Take the password off your own PDF: type the open password, or let the permission switches come off on their own. Rotate PDF ReadyOpen → Turn every page, or one range, a quarter or half turn. The file carries the turn; nothing is redrawn. Add page numbers ReadyOpen → Page numbers drawn onto the pages: bottom centre, outside corner or top, from the number you start at. Watermark PDF ReadyOpen → Stamp DRAFT or your own words across the pages, diagonal or straight, at the strength you pick. Extract images from PDF ReadyOpen → Pull the pictures stored in a PDF out as files, with a report naming anything that cannot come out. View and strip PDF metadata ReadyOpen → See the details a PDF stores about itself, exactly as stored. Fix the title or author, or wipe the whole label card. JPG to PDF ReadyOpen → Pictures into one PDF, one per page, in your order, exactly as stored. PDF to JPG ReadyOpen → Every page as a picture, screen or print size, in one ZIP in page order. Read a scan (OCR) ReadyOpen → Scanned pages read at 300 DPI: checkable text plus a searchable PDF. 96% character accuracy on the test invoice.
Batch and workflows
Batch compress PDF ReadyOpen → A folder of PDFs worked to one target size in a single run, per-file results, one ZIP out. The job the suites sell as a paid extra. Batch merge PDF ReadyOpen → Pick a whole folder, sort the tray by file name, and merge it into one file. Batch split PDF ReadyOpen → One page range cut from every file in the folder, in a single run. Workflows ReadyOpen → Chain the tools (merge, then shrink, then sign), save the chain in your browser, and run it on the next folder. Preset chains ReadyOpen → Ready-made chains for the weekly jobs: invoice pack, portal pack, paid pack, seller photos.
Image jobs
Compress image to exact KB ReadyOpen → The tool the big sites do not offer: a photo at the exact size a form or shop asks for. Compress image to 50 KB ReadyOpen → The form and seller preset: the same tool, with the 50 KB target already set. Batch compress images ReadyOpen → A folder of photos worked to one exact KB target in a single run, one ZIP out. Batch convert images ReadyOpen → A folder converted to JPG, PNG or WebP at one quality, with an optional maximum width. Read the words in a photo (OCR) ReadyOpen → Words out of a photo or screenshot as text you can check, copy and download. English, Spanish and Portuguese; 99% of characters right on the clean test picture. Resize image ReadyOpen → A photo to exact pixels: passport and post presets, percent, or your own numbers. The result prints dimensions and bytes, before and after. Batch resize images ReadyOpen → A folder to one pixel size in a single run, every photo keeping its own format. Tested with 50 files in one run. HEIC to JPG ReadyOpen → An iPhone HEIC photo as a JPG, PNG or WebP, full size and upright. The brightness-range change is stated before the run. PNG to JPG ReadyOpen → One PNG as a JPG for forms and shops. See-through parts are painted over a colour you pick. JPG to PNG ReadyOpen → One JPG as an exact PNG, for doors that require PNG. WebP to JPG ReadyOpen → One WebP as a JPG that everything opens. JPG to WebP ReadyOpen → One JPG as a WebP for websites, usually the lightest of the three. PNG to WebP ReadyOpen → One PNG as a WebP for websites, transparency kept. WebP to PNG ReadyOpen → One WebP as an exact PNG, transparency kept.
Check a file
Size checker ReadyOpen → Exact bytes, real format, dimensions, pages or duration, lined up against the doors portals set.

The same doors, grouped with the guides and comparisons around them, live on the all tools page.

What “free” means here

“Free” is not a tier. There is no bigger version of a tool waiting behind a payment, because the work happens on your device, not on our servers — there is almost nothing for a payment to buy. The written commitment, with the one real limit, is on the what free means here page.

Nothing leaves the device

Every job runs inside the page, in your browser. Files sent to a server: 0, by design — and you can watch the network panel while a job runs, on the check it yourself page.

No counter, no account

There is no daily limit because there is nothing to count. Nothing to sign up for, so nothing to cancel.

Full size, always

The size you uploaded is the size you download. No small free size and no big paid size, because there are no tiers.

Honest when it can't

If a tool cannot do a job well, the page says so before you pick a file — and if a job can't beat the original, you get your original back, with the sizes printed.

How a job runs

01

Pick a file

It is read into this page's memory, nowhere else.

02

The page works

An open-source program, loaded from this site, does the job on your device.

03

Take it away

Download the result. Close the page and the file is gone from memory.

Network witness: during a job, this page sends 0 files to any server. Watch it live, and learn the network-panel check, on the check it yourself page.

Your workbench

Job notes

Saved in your browser, nowhere else

Jobs you finish and settings you choose are noted here, in this browser's own storage. The notes hold names and sizes only; your files themselves are never stored, so download your result before you close the page. Nothing here is sent to us or anyone else.

No jobs yet. The tray is empty.

    Questions

    Where does my file go?

    Nowhere. Every tool here runs inside your browser, on your device. Files are read into the page, worked on, and offered back as a download; nothing is uploaded, and there is no server here that could receive them.

    Is it really free?

    Yes, at full size, with no account and no daily counter. The site will be paid for by ads on the pages; no ads run yet. The written commitment is on the what free means here page.

    Why does the background tool load a program first?

    The removal program (44.3 MB, in 11 checked pieces) is the tool itself. Your browser loads it once, checks it piece by piece, and saves it, so later visits start at once. Your photo is never sent anywhere.

    What else can I do here?

    Compress a PDF to an exact size, merge and split PDFs, shrink a photo to an exact KB, read a scan, sign and flatten forms, and run whole folders through the batch tools and saved workflows. Every door is listed in the ledger above.
