ExploreWhich Image Format Should You Use?
Stop guessing. Match the format to the content type for the best quality and smallest file size.
| Format | Best For | Compression | Transparency | Use Case |
|---|---|---|---|---|
| WebP | Default for web photos & graphics | 25–35% smaller than JPEG | Yes | Hero images, product photos, thumbnails |
| AVIF | Smallest files with fallback | 40–55% smaller than JPEG | Yes | Performance-critical pages with picture element fallback |
| JPEG | Fallback compatibility, email | Baseline (lossy) | No | Email templates, legacy systems, print submissions |
| PNG | Screenshots, text, sharp edges | Lossless (large files) | Yes | UI screenshots, logos as raster, diagrams with text |
| SVG | Logos, icons, illustrations | Vector (tiny for simple art) | Yes | Brand logos, icons, flat illustrations, charts |
| GIF | Short animations (legacy) | Limited color, larger files | Yes | Simple animations where video is not supported |
Quick decision framework
- Logo, icon, or flat illustration? Use SVG. Export PNG where SVG isn't accepted.
- Screenshot or UI with text? Use PNG (or lossless WebP for web).
- Photo for the web? Use WebP — or AVIF with a fallback for maximum compression.
- Photo for print or archiving? Use high-quality JPEG (90+) or a lossless master.
- Need animation? Use animated WebP for short loops, or MP4 for anything longer.
Compress and convert instantly
Pixly's Image Compressor reduces file size up to 80% with zero visible quality loss. Convert between JPEG, PNG, and WebP — all processed in your browser, no uploads required.
Open Image CompressorImage Optimization Checklist for Web Performance
Images are 50–70% of page weight and the #1 cause of poor Core Web Vitals. Run through this checklist before shipping.
- Serve AVIF as primary format with WebP and JPEG fallbacks using the <picture> element
- Always declare width and height attributes on every <img> to prevent Cumulative Layout Shift (CLS)
- Add fetchpriority="high" to your LCP (hero) image — never lazy-load it
- Apply loading="lazy" to all below-the-fold images to reduce initial page weight
- Use srcset and sizes attributes so browsers download the right resolution for each device
- Add decoding="async" to non-critical images to prevent main-thread blocking
- Compress to a target quality (AVIF ~50, WebP ~80) instead of guessing by eye
- Strip EXIF and metadata from production images to reduce file size and protect privacy
- Keep source images at 2000px+ for product photos so zoom works on mobile
- Serve images from a CDN with on-the-fly format conversion and resizing
Content Creator Photo Editing Workflow
Post daily across Instagram, TikTok, and YouTube without spending hours in post-production. A 25-photo batch takes under 20 minutes.
- Batch shoot: Capture a week's worth of content in one session — change outfits, angles, and locations
- Cull ruthlessly: Reject technical failures, choose winners within bursts, separate heroes from support shots
- Apply consistent base corrections: Exposure, white balance, and contrast across the full set first
- Remove distractions: Use AI object removal to erase photobombers, trash cans, and unwanted elements
- Remove backgrounds for cutouts: Create transparent PNGs for brand collaborations and sponsored content
- Enhance with AI: Auto-fix lighting, color, and sharpness with one click for visual consistency
- Resize for each platform: Export at 1080×1350 for Instagram feed, 1080×1920 for Stories and Reels
- Add watermarks to protect brand assets before publishing to public platforms
- Strip EXIF metadata before uploading to protect location privacy
- Review the full set side-by-side before export — consistency issues only show across a batch
E-commerce Product Photo Checklist
Product images do the selling before shoppers read a word. 56% of users inspect images first — make every shot count.
- Start with a clean hero image: Front-facing, distraction-free background, product clearly identifiable
- Include 5–8 images per product: Hero, back/side angle, detail close-up, scale reference, lifestyle shot
- Shoot at 2048×2048px minimum so pinch-to-zoom works on mobile devices
- Use consistent aspect ratios across all product images to prevent gallery layout shifts
- Remove backgrounds for a clean, consistent catalog look across collection pages
- Add lifestyle context: Show the product in use, in environment, or worn by a model
- Compress all product images to WebP or AVIF — target under 200KB per image
- Write descriptive, keyword-rich alt text for every product image for SEO and accessibility
- Place video early in the carousel (position 2–3) — 73% of consumers prefer video to learn about products
- A/B test hero images: Stores upgrading from flat-lay to lifestyle shots see 18–24% lift in add-to-cart rate

Open ToolFrequently Asked Questions
Quick answers to the most common image editing and optimization questions.
In 2026, the most common standard is 1080 pixels wide. Instagram feed posts work best at 1080×1350 (4:5 portrait), Stories and Reels at 1080×1920 (9:16), and square posts at 1080×1080. YouTube thumbnails should be 1280×720, and TikTok content uses 1080×1920. Use Pixly's Social Media Photo Resizer to automatically crop and resize for any platform.
Serve AVIF as your primary format with WebP and JPEG fallbacks using the HTML <picture> element. WebP is the best modern default — 25–35% smaller than JPEG with universal browser support. Use PNG only for screenshots or images with text, SVG for logos and icons, and JPEG as a legacy fallback. Pixly's Image Compressor can convert and compress your images to WebP instantly.
Start by serving modern formats (AVIF/WebP), always declaring width and height attributes, adding fetchpriority="high" to your LCP image, lazy-loading below-the-fold images, and using srcset for responsive delivery. Compress to a target quality rather than by eye. Strip unnecessary metadata. These steps directly improve LCP, CLS, and INP scores.
Research shows 5–8 images per product is the sweet spot. Include a hero shot (clean background, front-facing), alternate angles, detail close-ups, a scale reference, and at least one lifestyle shot. Shoot at 2048×2048px minimum so zoom works on mobile. Use Pixly's AI Background Remover for clean, consistent catalog images.
Batch shooting and batch processing are the biggest time-savers. Capture a week's worth of content in one session, then use AI tools to normalize lighting, remove distractions, and resize for each platform. A batch of 25 photos can be processed in under 20 minutes with AI, compared to 2+ hours manually. Pixly's Batch Image Processor handles compression, resizing, and format conversion in bulk.
Yes. Pixly processes all images entirely in your browser using WebGPU and WebAssembly. Your images never leave your device — there are no uploads, no servers processing your data, and no accounts required. All tools are free and unlimited. This architectural privacy means we literally cannot access your images.
AI upscaling uses a neural network (like ESRGAN) to reconstruct high-frequency details that don't exist in the source image. It doesn't just stretch pixels — it generates plausible detail based on learned patterns. Use it for slightly low-resolution images that need to be larger: profile photos, product images for high-DPI displays, or old photos for printing. Pixly's AI Image Upscaler supports 2x and 4x upscaling.
EXIF metadata can include GPS coordinates, timestamps, and device information. To strip it before uploading, use Pixly's EXIF / Metadata Remover — it removes all EXIF, GPS, and hidden metadata from your photos instantly, right in your browser. This protects your location privacy when sharing images on social media or public platforms.
