8 Quick Start Guides

Master File Optimization
in Minutes

Accurate, step-by-step guides for every tool - images, video, audio, GIFs, PDFs, and 3D models.

Image tools work without internet

Compress Images

Shrink JPEG, PNG, WebP, AVIF, JXL, and HEIC photos by 50-80% right in your browser. Your files never leave your device.

FREE

Step by Step

  1. 1Drag and drop images onto the upload zone, or click to browse (free: up to 25MB per file, 3 per batch)
  2. 2Open the file's settings and adjust the quality slider - 70-85% is the sweet spot for web use
  3. 3Pick an output format: WebP for best all-round compression, AVIF for maximum savings, or Keep Original to avoid converting
  4. 4Click Optimize to process the file locally on your device
  5. 5Use Compare to check the result side by side, then download

Good to Know

  • WebP is typically 25-35% smaller than JPEG at the same visual quality
  • Compression re-encodes the image, which strips EXIF metadata (location, camera info) - a built-in privacy bonus
  • Already-optimized files may not shrink much - converting to WebP or AVIF usually helps

Convert Image Formats

Convert between JPEG, PNG, WebP, AVIF, and JXL - including iPhone HEIC photos to universally supported formats.

FREE

Step by Step

  1. 1Upload the image you want to convert
  2. 2Open the file's settings panel
  3. 3Choose the target format from the output format dropdown
  4. 4Adjust quality if converting to a lossy format
  5. 5Optimize and download the converted file

Good to Know

  • HEIC photos from iPhones convert to JPEG or WebP for compatibility everywhere
  • Use PNG when you need lossless quality or transparency
  • AVIF needs a modern browser to encode (Chrome 85+, Firefox 93+)

Compress & Edit Videos

Compress MP4 videos with the H.264 codec, trim clips, and adjust colors - all processed locally with WebCodecs.

PRO

Step by Step

  1. 1Upload your MP4 video (Pro Lite: up to 100MB, Pro Deluxe: up to 250MB)
  2. 2Adjust the bitrate in settings - lower bitrate means a smaller file
  3. 3Optionally open the video editor to trim, cut, and adjust brightness, contrast, or saturation
  4. 4Click Optimize and wait while the video is re-encoded in your browser
  5. 5Compare the result, then download your optimized MP4

Good to Know

  • 5-8 Mbps is ideal for 1080p web sharing; 2-5 Mbps works well for 720p
  • Trimming unnecessary footage before compressing gives the biggest savings
  • Large videos take longer - processing speed depends on your device's CPU

Compress Audio

Compress MP3 files or convert WAV to MP3 with the LAME encoder, and trim tracks with the built-in audio editor.

PRO

Step by Step

  1. 1Upload your MP3 or WAV file
  2. 2Select the output format and bitrate in settings
  3. 3Optionally trim the track with the audio editor
  4. 4Click Optimize to encode the file
  5. 5Download the compressed result

Good to Know

  • 96-128 kbps is plenty for podcasts and voice; use 192-256 kbps for music
  • Converting WAV to MP3 typically cuts file size by 90% or more
  • Keep your original WAV files if you plan to edit the audio again later

Optimize GIFs & Create Animations

Compress animated GIFs, convert GIF to MP4 (up to 90% smaller), turn videos into GIFs, or animate still images.

FREE

Step by Step

  1. 1Upload a GIF, video, or still image
  2. 2For GIFs: compress directly or choose MP4 as the output format for huge savings
  3. 3For videos: select GIF output to create a shareable animated GIF
  4. 4For still images: choose Create Animation and pick an effect like zoom, pan, glow, rotate, slide, or bounce
  5. 5Optimize, preview the animation, and download

Good to Know

  • Converting a GIF to MP4 can reduce file size by up to 90% with better quality
  • The GIF editor lets you adjust frame timing and add text overlays
  • Fewer colors and smaller dimensions make dramatically smaller GIFs

Optimize 3D Models

Compress GLB 3D models with industry-standard Draco and Meshopt geometry compression, with a live 3D preview.

PRO

Step by Step

  1. 1Upload your GLB file
  2. 2Choose compression settings - geometry compression shrinks vertex data significantly
  3. 3Click Optimize to process the model in your browser
  4. 4Inspect the result in the interactive 3D viewer and compare against the original
  5. 5Download your optimized GLB (saved with an _optimized suffix)

Good to Know

  • Draco compression can shrink geometry data by 80-95% with minimal visual difference
  • Optimized GLB files load much faster in web viewers, games, and AR experiences
  • Textures often dominate file size - compressing embedded textures helps too

Compress & Edit PDFs

Shrink PDF documents by recompressing embedded images, and redact sensitive information before sharing.

PRO

Step by Step

  1. 1Upload your PDF document
  2. 2Adjust the compression level - embedded images are the biggest size factor
  3. 3Optionally open the PDF editor to redact sensitive content with removable redaction boxes
  4. 4Click Optimize to rebuild the PDF
  5. 5Download the compressed file (saved with a _compressed suffix)

Good to Know

  • Scanned documents compress the most since every page is an image
  • Text-only PDFs are already small - image-heavy PDFs see the biggest savings
  • Always double-check redactions before sharing sensitive documents

AI Upscale Images

Enlarge images up to 4x with AI that adds realistic detail instead of just stretching pixels.

PRO

Step by Step

  1. 1Upload the image you want to enlarge
  2. 2Open Upscale Settings on the file card
  3. 3Enable upscaling and choose a multiplier (2x or 4x) or a resolution preset (720p, 1080p, 4K)
  4. 4Click Optimize to generate the high-resolution version
  5. 5Compare the result and download

Good to Know

  • AI upscaling works best on photos with natural detail
  • Start with 2x - it preserves the most fidelity
  • Great for preparing low-resolution photos for printing
