Tools are organised by use — documents & images, text, developer jobs, generators, and everyday calculators — so you can find the right one in seconds. New: decode a QR code from a screenshot or straight from your clipboard, and paste images or text into the tools that accept them. Everything still runs locally, with nothing to upload.
Pick a category, then a tool. Or search across all 17.
For application forms, admissions and ID uploads that reject anything over a set size. Pick a target — the tool adjusts quality, and shrinks dimensions only if it has to — until the file fits.
Combine several PDFs into one, in the order you add them — or shrink a single PDF that is too big to email or upload.
Add two or more files. Pages are copied exactly as they are, so text stays sharp and searchable.
Rebuilds the pages as compressed images at the quality you pick. Best for scanned documents and photo-heavy files; text in the result is no longer selectable, so keep the original if you need that.
Smallest suits form uploads. Balanced is the safe default for sharing. Sharper keeps fine print readable.
Turn photos and screenshots into a single tidy PDF — one image per page, in the order you add them.
For menus, payment links, Wi-Fi, event pages — type anything and download a print-ready PNG. These are static codes: they never expire and point straight at your text or link.
Keep strong contrast between the two colours or scanners will struggle. Dark on white is the most reliable.
Tip: copy the image, then paste it straight into the QR Decoder below to check what it contains.
Read a QR code you already have — from a screenshot, photo, flyer or a code someone sent you. Drop the image, pick a file, or paste it straight from your clipboard. Nothing is uploaded; decoding happens on this device.
Clipboard needs your permission: when you tap “Paste image”, the browser may ask to allow clipboard access — choose Allow. On some phones the paste button isn’t available, so use “tap to choose” and pick the screenshot from Photos instead. You can also copy any image anywhere, open this tool, and press Ctrl+V / Cmd+V — it will decode automatically.
Screenshots work best when the QR fills a good part of the image and isn’t blurry or tilted. If a busy photo fails, crop tightly around the code and try again.
Strong passwords made with your browser’s secure random generator — the same source operating systems use. Nothing is sent anywhere, and generated passwords are never stored.
16+ characters is a solid default. Use the longest a site allows for important accounts.
Strength will be estimated here.
Counts as you type — essays, cover letters, posts and abstracts with a word limit.
Word frequency appears here once there is text.
Everyday conversions with no rounding surprises — recipes, travel, shipping weights, screen sizes and file sizes.
Paste JSON to pretty-print it, minify it, or find out exactly where it breaks. Runs locally, so API keys and payloads stay on your machine.
See the real cost of a loan before you sign — monthly payment, total interest, and a year-by-year payoff breakdown. An estimate for planning, not financial advice.
In your currency — the maths is identical either way. Default shown in VND-sized numbers; type any amount.
Two quick checks: body-mass index from height and weight, and your exact age — years, months and days — from a date of birth.
BMI is a rough population-level guide. It doesn’t account for muscle, build or pregnancy, and isn’t a diagnosis — talk to a clinician for personal advice.
Fix capitalisation in one click — titles for headings, sentence case for paragraphs, UPPER CASE for labels, or lower case for emails and URLs.
Encode text to Base64 for APIs, data URIs and config files — or decode a Base64 string back to readable text. Handles Unicode and emoji correctly.
Three everyday jobs: find a percentage of a number (discounts, tax, tips), work out what percent one number is of another, and see percentage change (price rises, grades, growth).
Pick a colour or type a HEX code and get the exact RGB and HSL values to copy into designs, CSS and documents.
Examples: #FF5733, #0D6A4C, #2563EB. The preview updates as you type.
For developers, logs and databases: convert a Unix timestamp to a readable date, or a date back to a timestamp. Current time is shown live below.
Now: — · —
Generate random version-4 UUIDs for databases, APIs and testing — using your browser’s secure random generator. Generate one or a batch of ten.
Free Online Tools is a single-page collection of 17 small, free utilities for everyday jobs: shrinking an image to an exact file size for a form, merging or compressing a PDF, turning photos into a PDF, making and reading QR codes, generating passwords and UUIDs, counting words, converting units, colours and timestamps, formatting JSON and Base64, and working out percentages, loan payments, BMI and age.
The tools are grouped by use — Documents & Images, Text & Writing, Developer Tools, Generators & Codes, and Calculators & Converters — so you can find the right one quickly. There is no account, no sign-up and no paywall.
Everything runs client-side, in your browser. Files you open are processed on your device and are not uploaded to a server by this site, which keeps the tools fast and private and keeps running costs near zero.

All 17 tools run locally in your browser. Files, images, PDFs and text you use in a tool are processed on your device only. They are not uploaded, transmitted or stored by this site, and we have no server that receives them.
To make the PDF, QR and font features work, the page loads open-source libraries and fonts from content delivery networks (jsDelivr and Google Fonts). Those providers may see a standard web request — your IP address, browser type and the file requested — under their own privacy policies. No tool content is sent with those requests.
The boxes labelled “Ad space” are currently empty placeholders — no advertising code, ad cookies or ad tracking runs yet. If advertising (for example Google AdSense) is added later, the ad provider may use cookies or similar technology to serve and measure ads, including personalised ads where you consent. This policy will be updated before any ad code goes live, and any consent controls required in your region will be added at that time.
No analytics or tracking scripts are included in this version of the site.
Because tool data never leaves your device, there is nothing for us to delete on request. You can clear any files a tool created by closing or reloading the tab. For any privacy question, use the Contact section below.
