Media & File Utilities

Tools for modifying images, compressing documents, and managing files securely on your device.

File tasks that used to require desktop software now run directly in the browser. Image resizing, PDF merging, audio trimming, and video compression all happen on your device — the file never leaves your machine, which matters when working with client files, medical documents, or personal media you would not normally upload to a third-party service.

What these tools cover

  • Meme Generator — Create custom image memes with classic top and bottom text.
  • PDF Merger — Merge multiple PDFs locally without uploading.
  • Image Resizer — Batch resize and compress images.
  • Video Compress — Calculate optimal bitrates for video compression.
  • Audio Trimmer — Cut and trim MP3 files.
  • Color Picker — Extract colors from images and convert HEX/RGB.

How to get accurate results

For images, set output dimensions to your actual required display size — resizing to the exact pixel dimensions eliminates most file size without quality loss, while oversizing wastes bandwidth and undersizing creates blurry results. For video, confirm the target platform's recommended bitrate before compressing — YouTube, Instagram, and TikTok each have different optimal settings. Arrange PDF pages in the correct order before merging, since rearranging requires restarting the process.

When to use these tools

  • Resizing product images to the exact pixel dimensions required by a storefront or CMS upload spec
  • Merging multiple PDF documents into one for submission, printing, or sharing with a client
  • Trimming an audio file to a specific length before embedding it in a presentation or video
  • Compressing a video file to fit within a platform's upload size limit without re-rendering from source
  • Extracting the exact HEX or RGB value of a color from an image to match it in a design tool

Frequently Asked Questions

What media tools are available?

Image resizer and compressor, video compressor (FFmpeg.wasm), PDF merger, QR code generator, barcode generator, color picker and converter, meme generator, and audio trimmer.

Are files uploaded to a server?

No. Every media tool in this category processes files locally using browser APIs — Canvas API for images, FFmpeg.wasm for video, PDF-lib for PDFs. Your files never leave your device.

What is the file size limit for video compression?

There is no hard limit — the constraint is your device's available RAM. Most devices handle files up to several gigabytes without issue.

Can I use these tools for confidential files?

Yes — because nothing is uploaded, these tools are safe for confidential documents, proprietary images, and sensitive video content.
