File Compressor

Make images, videos, PDFs and audio smaller, by strength or to the size you choose. Videos, audio and many images show an estimated size before you start.

Choose Light, Balanced or Strong, or give a size in KB or MB for each file to get under. Filebender works out the settings for each kind of file: pictures, videos, PDFs and audio.

Almost any file

Images, vector art, video, audio, documents, spreadsheets, slides, ebooks and archives: more than 400 conversions. Before anything runs, Filebender says what a conversion will lose and estimates the size of video, audio and many pictures; other files show their size once converted. It compresses PDFs, pictures and videos to the size you choose.

No ads, no watermarks

With a free account: 20 files a day, 2 of them videos, each up to 500 MB. No plan has ads, and nothing is stamped on your files. A pass is one payment that never renews, and one you haven't used can be refunded in full.

Private by default

Files are deleted an hour after converting, or at once when you ask, and photo location is removed unless you choose to keep it. Photos converted to JPG, PNG or WebP are done on your device when your browser can, so they never leave it. They still need your account and count towards your plan.

How to compress a file

  1. Create a free account with Google or your email address, or sign in.
  2. Choose your files: drop them on the box, pick them from your computer, open them from Google Drive, or paste a link.
  3. Choose how small: a strength, or a target size you choose. The gear button has more settings.
  4. Press “Compress”, then download each file, or all of them in one ZIP.

A strength, or the size you choose

Light, Balanced and Strong set the quality of pictures (88, 75 and 55 out of 100), the quality level of video, and the bitrate of sound (160, 128 and 96 kbps). With a size of your own, each file aims to land just under it, within 10%.

If a size can't be reached, Filebender says so and names the smallest it could make, so you can raise the size or resize the file. For a video it can tell before starting.

What each kind of file gives up

Photos lose fine detail that's hard to see. PNG stays lossless at any strength, and only a size limit makes it use fewer colours. Video is encoded again at a lower bitrate, and to reach a small size it may be scaled down to 360p. Sound loses detail you're less likely to hear. PDFs have their pictures made smaller while the text stays sharp and searchable.

Sizes before you start

Videos, audio and many pictures get an estimated size first, shown next to each file, so you can change the strength before converting. PDFs show their size once they're done. If a result comes out bigger than the file you started with, which can happen with files that were already well compressed, you can keep the original instead.

JPG and WEBP photos compressed by strength, rather than to a size, are often done on your device when your browser can, without uploading them. Each still needs your account and counts as a file against your allowance. PNGs are always compressed on the servers, where an extra optimiser makes them smaller.

Questions

Does compressing change the format?

No. A compressed file keeps its format, except on pages made for one job, such as the Audio Compressor, which saves MP3. When a format is the problem, converting helps more: an animated GIF made into an MP4 is usually far smaller.

Does the size I give apply to each file or the whole batch?

To each file. Ten photos with a limit of 2 MB come back as ten photos, each aiming to be under 2 MB.

Which files can't be made much smaller?

Files that are already compressed hard, such as MP3s at low bitrates or ZIP archives. Text-only PDFs are small already, so there's little to take out of them.

Is Filebender free?

Yes, with a free account: 20 files every day (up to 2 of them videos), each up to 500 MB, with no watermark and no ads. Make the account with Google or your email address. Files converted on your device count the same way as the rest. If you need more, a Day, Week or Month Pass is one payment that never renews; see the Pricing page.

Why do I need an account?

Every plan needs an account, including the free plan. Your daily allowance and any pass you buy are kept with your account, and accounts keep automated abuse out. Making one costs nothing, with Google or your email address, and you can start converting as soon as it's ready.

What happens to my files?

It depends on the file. Pictures your browser can convert itself, and everything you do with the PDF tools, from merging and splitting PDFs to putting photos into one, are handled on your device and never leave it, unless you choose to send a file to Filebender's servers. They still need your account: Filebender receives only their type and size, to count them against your plan like any other file. Everything else is converted on Filebender's servers on Google Cloud and deleted an hour after the conversion finishes, or straight away when you press “Delete files now”. Nobody looks at your files, and they're never used for anything else.
