The Multi-tool is free — and always will be
No accounts, no watermarks, no upload limits. If it saved you a headache, a small tip keeps it running and buys F.C. Marrow a coffee.
Got a picture in the wrong format, or one that’s too big to upload or email? Change it to a PNG, JPG, or WEBP and shrink it down in seconds. Do a whole batch at once — and it all happens on your device, so your photos stay private.
Switch a photo between PNG, JPG, and WEBP, and optionally make the file smaller. Perfect for meeting a website’s upload limit, trimming an email attachment, or turning a heavy image into a light one without losing much quality.
Fit a photo to the exact size a platform wants — square posts, stories, thumbnails, headers — with a clean center-crop or a padded fit.
Squeeze a photo under a target file size for uploads and email — pick a limit and it finds the best quality that still fits.
See what a photo quietly reveals — camera, date, even GPS location — then download a clean copy with all of it stripped before you post.
Runs an AI model on your own device. The first use downloads it (once); after that it’s instant to start. Give each image a few seconds — big ones take longer on slower machines. Nothing is ever uploaded.
Stamp your own logo or signature onto your photos — add one watermark, or two, one in each bottom corner. Batch a whole folder at once. Your images and your logo never leave your device.
Drop in the photos you want to protect, then add your own watermark image (a transparent PNG works best). Use one corner or both.
Your watermarks — up to two
They size and place themselves automatically. Each watermark is scaled to about a tenth of the photo’s width and tucked a small, even margin in from the corner. Wide landscape shots get smaller marks so they don’t take over; tall portrait shots get proportionally larger ones — and because the spacing is measured in percentages, both marks land in exactly the right spot at any size or orientation.
Text watermark — optional

Pull the audio out of a video to listen on the go, or change a video or song into a format your phone or player will actually open. It handles the everyday ones — MP4, MKV, MOV, MP3 and friends. The very first conversion loads a small engine (about 30 MB, just once); after that you’re good.
Turn a video into an MP3 for the car, convert an MKV your player refuses to open into a standard MP4, or grab the sound from a clip. Drop the file, choose what you want out, and go. Large videos take a few minutes — your computer is doing the heavy lifting, and none of it is uploaded.
The everyday PDF jobs people usually hunt for a website to do — stitch files together, pull out the pages you need, make a PDF from photos, or turn a PDF back into images. All of it happens right here, with nothing uploaded.
Have a few separate PDFs that really should be one document? Drop them in the order you want and get a single combined file back.
Only need a few pages out of a big PDF? Type the ones to keep — like 1-3, 5, 8-10 — and get a tidy new PDF with just those.
Turn photos or scans into one clean PDF, a picture per page. Handy for sending receipts, a signed form, or artwork as a single tidy file.
Save every page of a PDF as its own picture — great for posting, printing one page, or dropping a page into a slideshow. You’ll get them all bundled in one ZIP.
Reorder or delete pages, and rotate if a scan came in sideways. Type the page order you want — anything you leave out is dropped. e.g. 3,1,2,5-7.
Stamp clean page numbers along the bottom of every page. Choose where they sit and what number to start from.
Pull the selectable text out of a PDF into a plain .txt file — handy for editing, quoting, or word-counting. (Scanned images have no text to extract.)
Need a Word document as a PDF so it looks the same for everyone and can’t be easily edited? Drop the .docx in and get a PDF back — without installing Word or uploading your file anywhere.
Good for everyday documents. Letters, essays, resumes, and reports come out looking right. Very fancy layouts — unusual fonts, tight columns, heavy tables — can shift a little, because a browser can’t perfectly copy desktop Word. If a document like that matters, open the PDF and give it a quick look.
Little design helpers — pull a palette from any image, wrangle color codes with an accessibility check, spin up a QR code, or generate a full favicon set for a website.
Drop an image and pull its main colors as HEX — perfect for mood boards and brand kits. Tap a swatch to copy it.
Convert between HEX, RGB, and HSL, and instantly check whether two colors meet accessibility contrast (WCAG) for readable text.
Turn a link, your socials, or your Ko-fi into a scannable QR code you can print or post. Downloads as a crisp PNG.
One square image → every icon size a website needs, plus a real favicon.ico and a copy-paste HTML snippet, bundled in a ZIP.
Get a post ready before it goes out — check caption length for every platform, style your bio, keep Instagram’s spacing, tidy your hashtags, and build trackable links. (Posting itself happens in whatever app you like — these make the content perfect first.)
Type your caption once and see if it fits everywhere at a glance — X, Threads, Bluesky, Instagram, TikTok, YouTube, LinkedIn.
Turn plain text into 𝗯𝗼𝗹𝗱 and 𝑰𝒕𝒊𝒍𝒊𝒌 unicode styles for Instagram, TikTok, and LinkedIn bios (which don’t allow real formatting). Tap Copy on the look you want.
Note: screen readers can’t read these styled letters well — use them for a name or an accent, not your whole caption.
Instagram collapses your paragraph breaks. Write your caption with the spacing you want, copy it from here, and the blank lines survive the paste.
Type what your post is about and get a batch of relevant hashtags — from related-word suggestions plus a built-in library of popular tags by niche. Tap any to send it down to the Manager. (Topic-based ideas, not live trend data.)
Paste a pile of hashtags — it cleans them up, drops duplicates, counts them, and warns if you pass Instagram’s 30. Save your go-to sets to reuse anytime.
Add UTM tags to a link so your analytics show exactly which post or platform drove each click — perfect for your link-in-bio.
Fast writing helpers — count words and reading time as you type, or clean up and reformat a block of text in a click.
Paste or type below. Everything updates live — great for query letters, essays, captions, and platform limits.
Reformat text in a click, or tidy up messy pasted copy — straighten smart quotes, kill double spaces, and more.
