In shortBrowser file tools are about 115 converters and editors for images, PDFs, office documents, video and audio, at /tools/<name>. Your files are processed in your own browser and never uploaded. Each tool gives you one free run per day. After that, a run costs credits and needs a free account. One run is one press of the tool's main button, however many files are in that batch.

What the file tools are for

Website work involves a lot of file chores: shrinking images before upload, turning iPhone HEIC photos into JPGs, making a favicon, merging PDFs, pulling the audio out of a video. The file tools handle those without installing anything. Because the processing happens on your device, they also suit files you'd rather not send to a stranger's server.

For SEO, the image tools matter most. Large images slow pages down, and slow pages hurt Core Web Vitals. Converting photos to WebP or AVIF and compressing them before upload is one of the cheapest speed fixes there is. Clear file names and the right dimensions help too.

What's in the set

Use a file tool

  1. Open the toolGo to the tool's page, for example PNG to JPG. Metered tools carry a "1 free run a day" tag, and the line under the button tells you how many free runs you have left today.
  2. Choose your filesDrag files onto the drop area or tap it to pick them. It says Choose files, or names the file type, such as Choose PNG images. The list shows each file with a thumbnail; you can remove or reorder them. Many tools take several files at once.
  3. Set options, if anyMost tools work with the defaults. Options are labelled in real units such as pixels, KB, percent or DPI. Changing options and previewing is free.
  4. RunPress the tool's main button, for example Convert to JPG. That press is the one run. A progress bar shows "x of n" for longer jobs. For editors such as crop or sign PDF, you work freely and the run is spent when you apply or download.
  5. DownloadDownload each file, or use Download all (.zip) when there are several.

How the free run and credits work

  • Each tool gives one free run per day. The day resets at midnight India time (IST), so outside India the reset falls at a different local hour.
  • Signed in, the free run is counted on your account. Signed out, it's counted per internet connection (IP address).
  • After the free run, you need to sign in, and each extra run costs credits. Heavy tools (background removal, upscaling, OCR, RAW photos and the video tools) cost more than the rest.
  • One run covers the whole batch you selected, so ten images in one press cost the same as one.
  • If a run fails in your browser, it's handed back automatically: the free run is restored or the credits refunded. That works within 15 minutes and up to three times a day.
Shared connections share the free run

Signed out, everyone on the same connection shares one free run per tool. Offices, public Wi-Fi and some mobile networks put many people behind one address, so you may find today's run already used. A free account gives you your own free run each day.

Batch your files

Because a run is one button press, put all the files for a job into one batch: compress the whole folder of blog images at once instead of one by one. The video tools, and some audio tools, download a converter engine into your browser the first time (about 30 MB, once); after that, conversions start straight away.

Check yourself

1. You compress 12 images with one press of the Compress button. How many runs is that?
2. Where are your files processed?
3. You're signed out at a co-working space and the tool says today's free run is used, though you haven't used it. Why?
