20 tools that do the work for most visitors

These are the tools people actually come back for. Each runs free, in your browser or in a stateless processing request, with no account and no watermark on the output.

🖼️Image CompressorShrink JPG, PNG and WebP photos with a quality slider and an optional maximum size, one image at a time or in bulk (bulk returns a ZIP). The output is JPEG. Handy when a photo is too heavy for an email, an upload form or a product page. 📄Compress PDFShrink a PDF for email and portal caps. Low rebuilds the file without touching images; medium and high re-encode embedded photos as JPEG (quality about 50 / 25). Text stays as vectors. Savings depend on the file — scans shrink a lot, text-only PDFs often barely move. Free, no signup. 📑Merge PDFsCombine several PDFs into one file in the order you drag them. Each page keeps its size and orientation. Bookmarks are rebuilt into the merged outline; fillable fields usually come along — open the download to confirm. Free, no signup. ✂️Background RemoverUpload a JPG, PNG or WebP photo and get a PNG with the background made transparent. The AI model is tuned for people, and other clear single subjects usually work too. Up to 20 images at once download as a ZIP. Phone photos stay upright; images over 2048 px are scaled down. 📐Resize ImageResize a photo to exact pixel dimensions up to 4096 px, or set one side and leave the other at 0 to keep its proportions. Optional center crop to 1:1, 4:3, 16:9, 3:4 or 9:16. Phone photos stay upright, and the result downloads as a JPG. 📝PDF to WordConvert a PDF into an editable Word (.docx) file: text, fonts, simple tables and images come across so you can change the wording. Works on PDFs with selectable text; scanned pages come through as pictures, because there is no OCR. Up to 20 PDFs at once (ZIP). 📱QR Code GeneratorTurn a URL or any text (up to 2,000 characters) into a black-and-white QR code PNG from 64 to 512 pixels, with an optional logo in the center. Static codes with no sign-up, no scan tracking and no expiry date. { }JSON FormatterPretty-print JSON with two-space indentation, minify it to one line, or find out why it will not parse. The error comes from your browser's JSON parser and points to the first bad character. Runs in your browser, so your payload is not sent to our server. 📝Word CounterCount words, characters with and without spaces, sentences and paragraphs as you type, plus reading and speaking time. Useful for essay limits, social posts and meta descriptions. Counting runs in your browser. 🔤Base64 Encoder / DecoderEncode text to Base64 or decode it back. UTF-8 safe, so accents and emoji survive the round trip. Useful for data URLs, email source and reading a JWT header. Runs in your browser, so the text is not sent to our server. 🔒Hash GeneratorGenerate SHA-256, SHA-384, SHA-512 or MD5 hashes of any text. Useful for comparing values, building cache keys and checking an expected digest. Hashing runs in your browser, so the text is not sent to our server. 🎨Color PickerChoose a color with the swatch, or use the eyedropper in Chrome and Edge to sample any pixel on your screen. Then copy its HEX, RGB or HSL code with one click. 🔑Password GeneratorGenerate a random password from 8 to 128 characters using lowercase, uppercase, numbers and symbols, with an option to skip look-alikes such as 0 and O. Shows the entropy in bits. Generated in your browser and never sent to our server. 📄Text to PDFPaste plain text, choose a font size (8–72) and A4 or US Letter, and download a PDF. Long text flows onto as many pages as it needs, line breaks and indents are kept, and the words stay selectable. Good for notes, logs and hand-ins that must arrive as one file. 📑Split PDFSplit a PDF into one file per page, or type ranges such as 1-5, 8, 11-13 and get one PDF for each range, all in a ZIP. Pages are copied as they are, so text stays sharp and selectable. Handy when only the signature page or one chapter has to go to someone else. 🔄Image Format ConverterConvert a JPEG, PNG or WebP image to JPEG, PNG or WebP. Output quality is fixed at 90 for JPEG and WebP. No BMP, GIF, TIFF or HEIC on this page. Transparent PNGs become white when saved as JPEG. Free, no signup. 🖊️PDF EditorAdd text, signatures, highlights and images, white out mistakes, and reorder pages, then download. Auto-redact removes matched emails, card numbers, phone numbers and US SSNs from the file instead of covering them — search the download to confirm. Files sit in a temporary session (deleted within about an hour). Free, no Adobe subscription. ▶️YouTube Thumbnail DownloaderPaste a YouTube video, Shorts or live link (or the video ID) and see the thumbnail in the five sizes YouTube stores, from 120×90 up to 1280×720 when the video has one. Download any size as a JPG. The link is never sent to our server. 🎬Video Logo RemoverCover a fixed logo, date stamp or small object in a video you own. Draw a box over it, choose Fill or Blur, and download an MP4 with the audio kept. Works on logos that stay in one place; moving overlays are not tracked. 🧾Invoice GeneratorFill in your details, the client, line items (Item | Qty | Unit price), one tax rate and an optional logo, and download a PDF invoice. Line amounts, subtotal, tax and total are worked out for you, and long lists continue onto extra pages. Nothing is saved on our server. (.*)Regex TesterTest a JavaScript regular expression against sample text. Matches highlight as you type, and each match lists its position and its numbered and named capture groups. The i, m, s and u flags are one click away. Runs in your browser.

Built by one developer, deliberately kept simple

GoToolsOnline is an independent project built and run by Ben Praveen J, a full-stack developer in Tamil Nadu, India. The brief was narrow: build the kind of tools site I personally wished existed — one that does not ask for an account, does not stamp watermarks on your output, does not limit free usage to two files per day, and does not bury a 30-second task under a "Start Free Trial" button.

The site does not host thousands of templated variations of the same converter. Every tool here was written for this site and is maintained by the same person who answers contact@gotoolsonline.com. If something breaks, it gets fixed. If a tool is missing, email and I will often build it.

Pages people already open from search: PDF to Word free online, compress a PDF for government forms, the word counter, and the image compressor.

How your files are handled

Text tools like the word counter, JSON formatter, Base64 encoder, and hash generator run entirely in your browser — the data you paste never leaves your computer. File tools like PDF compress, image compression, and background removal upload over HTTPS, process in server memory, return the result, and discard the original. There is no archival storage path for user uploads. Connections use TLS; analytics are anonymised (IPs are hashed); cookie consent is handled through Google Consent Mode v2 with explicit accept and reject controls.

How this is funded

One revenue source: Google AdSense. No paid tier, no premium plan, no credit-card form hiding behind a feature. Ads pay for the VPS, the domain, and a little compensation for the time that goes into building and maintaining the tools. If you prefer, the cookie banner lets you decline personalised advertising — the tools still work the same either way. Read the full story on the about page.

Frequently Asked Questions

What happens to a file after I upload it?
File tools (PDF, image, media) receive your upload over HTTPS, process it for your request, return the result, and discard the original. The PDF editor keeps its working copy in a temporary session that is deleted within an hour. Paste-based tools such as the word counter, JSON formatter, Base64 and hash generator run in your browser and do not send what you paste. See the privacy policy for details.
Are outputs watermarked or quality-limited?
No. The file you download is exactly what the tool produced: no watermark, no logo, no "upgrade to remove this" prompt. There is no paid tier, so the free PDF compressor, image compressor and background remover are the full versions.
What file size limits apply?
Uploads are capped at 500 MB per request. Big files take longer to upload and process, so for very large PDFs it is often faster to split or compress them first. There is no daily usage cap.
Which tool should I start with?
Most visits start with one of these: Edit PDF to add text or a signature, Compress PDF for upload limits, Image Compressor for large photos (it also has a Bulk mode that returns a ZIP), JSON Formatter for API payloads, and Word Counter for essays. Or browse a hub: PDF tools, image tools, text tools.
Who builds and runs GoToolsOnline?
The site is built and maintained by Ben Praveen J, a full-stack developer based in Tamil Nadu, India. There is no team, no investor, no VC — the same person who writes the tools also answers contact@gotoolsonline.com. You can also verify the human on the other side via LinkedIn.
