What Each Tool Is Actually For
PicResize is one of the original online image resizing tools, launched in the early 2000s. Its core functionality is simple: upload an image, choose new dimensions or a percentage reduction, pick a format, and download. It also offers basic cropping and a straightforward batch resize for multiple files. The interface has changed little over the years.
TinyPNG Now is a modern browser-based image optimization suite. It covers compression (PNG, JPG, WebP, HEIC, GIF), resizing, cropping, background removal, watermarking, format conversion, image upscaling, and photo editing -- 29 tools in total. Most processing happens locally in your browser and nothing is uploaded to a server (the background remover is the one exception and uses a cloud AI service).
💡 Key insight: PicResize does one thing adequately. TinyPNG Now does everything PicResize does and adds modern format support and 20+ additional tools -- all without uploading your images.
Compression Quality
TinyPNG Now re-encodes PNG, JPG, WebP and HEIC files in your browser with an adjustable quality setting. It uses smarter algorithms than standard export -- PNG compression strips unnecessary metadata and color palette entries; JPEG compression applies perceptual quality tuning that preserves detail where the eye notices it most.
PicResize offers a JPEG quality slider (Low, Medium, Good, Excellent) when saving as JPG. This is basic re-encoding rather than optimized compression. For web performance optimization, PicResize's compression is not in the same class.
✅ Winner: TinyPNG Now -- purpose-built compression delivering strong file size reduction across all major formats.
Privacy and Data Handling
PicResize is a server-side processing tool. When you upload an image, it travels to PicResize's servers, is resized on the server, and is returned as a download link. Your image exists temporarily on a third-party server. For most personal photos this is fine, but for product images, client work, or confidential content, this is worth considering.
TinyPNG Now processes everything in your browser. The moment you drop a file onto the page, it is decoded by JavaScript running on your own machine. No network request is made for your image data.
✅ Winner: TinyPNG Now -- no server upload for most tools; processing is browser-local.
Format Support
TinyPNG Now supports PNG, JPG, WebP, HEIC (iPhone photos), GIF, BMP, TIFF, and SVG depending on the tool. It can convert between formats -- for example, batch-converting a folder of HEIC files from an iPhone to WebP for a website. WebP output is particularly valuable for web performance, often achieving 25–34% smaller files than equivalent JPGs at the same visual quality.
PicResize supports JPG, PNG, and GIF. It does not handle HEIC files from modern iPhones, cannot output WebP, and does not support BMP or TIFF input. For anyone working with modern camera or phone formats, PicResize's format support is a significant limitation.
✅ Winner: TinyPNG Now -- WebP, HEIC, and modern format support that PicResize lacks entirely.
Bulk Processing
TinyPNG Now's bulk compressor accepts many files dropped at once. It compresses each file in parallel and offers a single-click ZIP download containing all optimized images. The bulk resizer works the same way -- set target dimensions once, apply to all files simultaneously.
PicResize does have a batch feature accessible from its main page. It allows uploading multiple images and applying the same resize settings to all of them. However, it is limited to resizing only -- there is no bulk compression, no format conversion, and no bulk background removal. The batch feature also uses server-side processing, meaning all images are uploaded.
✅ Winner: TinyPNG Now -- bulk compression, resizing, and conversion in one workflow; no upload required.
Breadth of Tools
PicResize offers three tools: resize, crop, and a basic batch resizer. That covers the most common simple use case, but nothing else.
TinyPNG Now offers 29 tools, including compress, resize, crop, rotate, background remover, watermark, upscaler, photo editor, color picker, EXIF remover, PDF to image, image to PDF and more. All tools are free and accessible from the homepage navigation.
✅ Winner: TinyPNG Now -- 29 tools vs 3. A complete image workflow in one place.

Frequently Asked Questions
Can PicResize compress images like TinyPNG?
Not at the same level. PicResize offers a basic JPEG quality slider, but it is not a dedicated compression tool. TinyPNG Now compresses with an adjustable quality slider and can convert formats.
Does TinyPNG Now resize images too?
Yes -- TinyPNG Now has a dedicated image resizer that supports pixel dimensions, percentage scaling, and preset sizes (1080p, 4K, social media dimensions). It also supports bulk resizing of multiple images at once.
Can PicResize handle iPhone HEIC photos?
No. PicResize only supports JPG, PNG, and GIF. Modern iPhones save photos as HEIC files. TinyPNG Now fully supports HEIC input and can convert to JPG, PNG, or WebP.
Is TinyPNG Now more complicated than PicResize?
No -- TinyPNG Now has a simple drag-and-drop interface for every tool. It offers more options, but each tool page is as simple to use as PicResize's resize page. You do not need to use all 29 tools if you only need one.
