Editing passport and ID photos for government applications

Government portals across the world enforce strict requirements for uploaded photographs. The US Department of State mandates 600×600 pixel photos at 300 DPI for passport applications, with the face occupying 70–80% of the frame. India's Passport Seva portal requires 630×810 pixels at 200 DPI with a plain white background and no glasses. The UK Home Office specifies 600×750 pixels at a minimum of 300 DPI. The UK Visa and Immigration (UKVI) system, the US DS-160 visa form, and the Schengen visa application portal all have their own dimension and file size specifications.

The real problem with passport and ID photos isn't the resizing — it's the privacy risk. A passport photo contains your face against a plain background, often alongside GPS coordinates, camera model, and timestamp embedded in the EXIF data. Most free online editors ask you to upload this to their cloud. PixelFix Pro keeps everything in your browser. Load the page, resize your photo, download it — the image data stays on your computer the entire time. You can verify this by disconnecting from the internet after the page loads; every tool still works.

Batch processing e-commerce product images for online marketplaces

If you sell products on Amazon, Shopify, Etsy, eBay, or Walmart, you already know that each marketplace has its own image size requirements. Amazon requires a minimum of 1000 pixels on the shortest side for its zoom feature, with 1600×1600 being the recommended size. Shopify suggests 2048×2048 pixels for crisp product images that scale well across devices. Walmart mandates 2200×2200 pixel images for its marketplace. And these are just the dimension requirements — you also need consistent square formatting, proper file sizes (under 10MB for Amazon), and optionally a watermark across every image.

Doing this one photo at a time in a traditional editor is painfully slow. The Batch Editor handles it: drop up to 50 images, select your marketplace preset (auto-fills the correct dimensions), choose a resize mode, and process them all. Every image gets the same treatment — same dimensions, same format, same watermark position — and the results download as a single ZIP. All processing runs in your browser via OffscreenCanvas, so a batch of 50 product photos finishes in under a minute on a modern laptop.

Your product photos — unreleased packaging designs, proprietary photography, seasonal collections — have real commercial value. They stay on your device from the moment you drop them in to the moment you download the ZIP.

Converting HEIC photos from iPhone for universal compatibility

Apple's iPhones have used HEIC (High Efficiency Image Container) as the default photo format since iOS 11. HEIC offers better compression than JPEG — typically saving 40–50% file size at comparable quality — but the format has limited support outside the Apple ecosystem. The practical consequence is that HEIC photos from your iPhone often cannot be uploaded to government portals, job application websites, many e-commerce seller platforms, or printed at pharmacy kiosks. They may not open correctly in older versions of Adobe Photoshop, Windows Photo Viewer, or certain email clients when attached directly.

Converting HEIC to JPEG should be simple, but most online converters ask you to upload your iPhone photos to their server. Given that HEIC files often contain GPS coordinates, timestamps, and device serial numbers in the EXIF data, that's a privacy risk. PixelFix Pro converts HEIC to JPEG using the heic2any library, entirely in your browser. Your photo is decoded, re-encoded as JPEG at 92% quality, and downloaded — all within browser memory, nothing sent anywhere.

Beyond HEIC, the tool supports automatic conversion of HEIF files and allows you to load BMP, GIF, and TIFF formats as well. If you need to convert HEIC to PNG instead (for transparency support) or to WebP (for smaller file sizes), simply change the output format in the Export panel before downloading. For bulk conversion of multiple HEIC files, the Batch Editor handles them all at once — outputting each as JPEG and packaging everything into a ZIP download.

Preparing images for social media platforms with exact pixel requirements

Every social media platform has its own optimal image dimensions, and using the wrong size can result in awkward cropping, low-quality thumbnails, or images that simply look unprofessional in the feed. Instagram square feed posts require 1080×1080 pixels. Instagram portrait posts (the 4:5 ratio that takes up more vertical space in the feed) need 1080×1350. Instagram Stories and TikTok videos use 1080×1920 in the 9:16 vertical format. Facebook link posts display best at 1200×630 pixels. LinkedIn posts work well at 1200×627, and X (formerly Twitter) in-stream images perform best at 1600×900. YouTube thumbnails have a standard size of 1280×720 pixels. Pinterest pins are most effective at 1000×1500 pixels.

PixelFix Pro includes all of these as presets in the Resize dropdown. Selecting a preset fills the exact pixel dimensions and locks the aspect ratio so your image doesn't stretch. Crop to refine framing, adjust brightness or contrast if needed, and download in JPEG or PNG. The whole process — from drop to download — takes under 30 seconds, everything running locally in your browser.
