PixelKit uses the RMBG-1.4 AI model from Bria AI to remove image backgrounds in one click. The model runs in your browser — your image never leaves your device.

How to Remove a Background

1. Open the ✂️ Remove Background tab
2. Upload your JPG, PNG or WebP (the AI model loads once, ~40 MB, then caches)
3. Choose a background replacement: Transparent PNG, White, Grey, Green Screen, or custom
4. Set Edge Softness (0 = sharp cut, higher = feathered edges)
5. Enable Hair & Fine Detail Mode for photos with detailed hair or fur
6. Click Remove Background — result appears in seconds
7. Use the Restore / Erase brush to fix any areas the AI missed

Best Results Tips

• Good contrast between subject and background gives the cleanest mask
• Plain, evenly-lit backgrounds produce near-perfect results every time
• Use the manual brush to restore fine hair detail the AI may miss

Steps

1. Upload your image — the AI removes the original background automatically
2. Choose a background type: Solid colour, Gradient, Blur or Custom image
3. For Solid: pick a colour from the swatch or enter a hex value
4. For Gradient: choose one of 12 presets and set the direction
5. For Blur: the original image is blurred and used as the background — great for portraits
6. For Custom: upload any background image and choose Cover, Contain or Stretch fit
7. Click 🎨 Change Background and download the result

Best results

• Clear subject contrast gives the cleanest AI cut
• Green Screen (#00ff00) or Blue Screen (#0000ff) options are available in the Solid colour preset list
• Use the ✂️ Remove Background tool for manual edge refinement before changing the background

Large images are the number one cause of slow websites. A single uncompressed photo can be 5–8 MB. The same image, properly compressed, can be under 200 KB with no visible difference.

Format Guide

Quality Settings

• Low (95%) — near-lossless. Hero images, banners
• Medium (82%) — recommended. Blog images, thumbnails
• High (65%) — moderately smaller. Background images
• Max (40%) — smallest file. Thumbnails, icons

Typical Results

• 5 MB JPG photo → 180–320 KB WebP (94% reduction)
• 2 MB PNG screenshot → 80–150 KB WebP (93% reduction)

Resize Modes

• By Pixels — enter exact width and height. Enable Lock aspect ratio to prevent distortion
• By Percentage — scale up or down relative to the original (e.g. 50% = half size)
• By Width — set width, height calculates automatically
• By Height — set height, width calculates automatically

Common Sizes

Tips

• Use PNG output for screenshots, graphics and images with text
• Use JPG at 90%+ quality for photos to keep file sizes small
• WebP gives the smallest file size with no visible quality loss

Getting your Instagram image sizes right is one of the most important things you can do to make content look professional. The wrong dimensions lead to cropped images, blurry uploads and reduced reach.

Instagram Sizes — Quick Reference

4. Fine-tune using the pixel coordinate inputs below the image
5. Click Crop & Download to save at full resolution

Aspect Ratio Quick Reference

Tips

• Use PNG output for completely lossless results
• The crop happens entirely in your browser — nothing is uploaded

• Use the Flip horizontal / Flip vertical buttons to mirror the image
• Use the Straighten slider (−45° to +45°) to fix tilted photos — the image auto-crops to remove white corners
• Click Apply & Download

Tip

• For best straightening results, find a horizontal reference line in the photo (horizon, tabletop, door frame) and align it visually using the grid overlay

1. Upload your image
2. Drag the Corner Radius slider or type a value in pixels

• Printed at 300 DPI — PixelKit exports at exactly 300 DPI

Short-form vertical video is the fastest-growing content format on the internet. TikTok, Facebook Reels and YouTube Shorts all use the same 1080×1920 (9:16) format — one export works on all three platforms.

Method 1: Create a Reel from Photos

1. Open the 🎬 Reels Maker tab
2. Drop your photos into the upload zone — bulk import supported
3. Set slide duration using the slider (2–3 s per slide is optimal)
4. Pick a transition: Fade, Slide Left, Slide Up, Zoom In, Zoom Out, or Cut
5. Add a text caption with animation (Fade, Typewriter, Bounce…)
6. Import background music (MP3/WAV/OGG)
7. Click ▶ Preview to watch the reel, then 🎬 Export Reel

Method 2: Split a Recorded Video

1. Open the ✂️ Video Splitter tab
2. Upload your MP4, MOV or WebM recording
3. Choose Auto split (by duration), By count, or Manual cut points
4. Click Analyse & Preview Clips
5. Download each clip individually or all at once

Optimal Reel Duration by Platform

Split Modes

• Auto (equal clips) — divides the video into equal-length clips. Set the duration slider to 15 s (TikTok), 30 s, or 60 s (Reels/Shorts)
• By clip count — enter how many clips you want. The video is divided equally
• Manual cut points — enter exact timestamps in seconds, comma-separated. Example: 30, 75, 120 creates cuts at 0:30, 1:15 and 2:00

Steps

1. Upload your MP4, MOV or WebM video
2. Choose a split mode and duration
3. Use the TikTok / Reels / Shorts quick buttons to set the right duration
4. Click ✂️ Analyse & Preview Clips
5. Each clip records in real time — a 30 s clip takes about 30 seconds to process
6. Download clips individually or use Download All

Important notes

• Processing is real-time — a 10-minute video split into 60 s clips takes ~10 minutes total
• Use Chrome or Edge for best results
• If a clip fails with a timeout error, try splitting into shorter segments

Platform Presets

Steps

1. Drop your audio files (MP3, WAV, FLAC, AAC, OGG, M4A, AIFF)
2. Click the platform card that matches your upload destination
3. Optionally enter track metadata (title, artist, album, year)
4. Enable Normalize loudness to match the −14 LUFS streaming standard
5. Click 🎵 Convert All Tracks
6. Download each track individually or use Download All

Important notes

• Converting a low-quality MP3 to hi-res WAV does not add quality that wasn't in the original — start from the highest quality source you have
• FLAC encoding loads a small WASM library (~2 MB) on first use
• Apple Music, Amazon and Spotify require files to be submitted through a music distributor (DistroKid, TuneCore, CD Baby etc.) — PixelKit prepares the files to the correct technical specification
