Every project has the same problem: the image is in the wrong format for the destination. Your photographer delivers TIFFs, the print vendor wants TIFF, Shopify wants JPEG, the web developer asks for WebP, and the email campaign needs JPEG again. Your iPhone shot everything in HEIC.

This guide covers the format conversions that come up constantly in visual production work — which format to use for which purpose, what you lose in each conversion, and how to handle the ones that are technically more complex.

Direct answer. Convert TIF to JPEG for web and digital delivery (JPEG is universally accepted, TIFF is not). Convert PNG to WebP for web performance (25–35% smaller, full transparency support). Convert HEIC to JPEG for anything outside Apple devices. Keep TIFF for print production and archival. Keep PNG for transparency-dependent assets in non-web contexts.

TIF to JPEG: When and How

TIFF is the professional standard for print, press, and archival workflows. It's lossless (every pixel preserved), supports multiple layers, and handles full color depth (8-bit, 16-bit, and 32-bit per channel). The downside: file sizes that run to hundreds of megabytes for print-resolution images.

For web delivery, TIFF is impractical — browsers don't render TIFF natively, and the file sizes would make pages unusable. Converting TIF to JPEG for digital delivery is the standard workflow.

What you lose in TIF to JPEG conversion: JPEG is lossy — it discards sub-perceptual image data during encoding. The data removed at quality 85–92 is genuinely invisible at normal viewing distances and screen sizes. At quality 70 and below, JPEG artefacts appear in fine detail (label text, fabric texture, hair). Converting at quality 82 with mozjpeg preserves the visual quality of the TIFF while reducing file size by 90–98%.

When to keep TIFF: Any time the file will go to a print vendor, repro house, or professional imaging application. Most commercial print workflows specify TIFF as the preferred submission format. Converting to JPEG and then back to TIFF for print introduces one lossy generation of compression — always keep the original TIFF and convert fresh for each delivery destination.

How to convert: Upload your TIFF to Playyy's image converter, select JPEG as the output, and download the result. The conversion uses Sharp's libtiff processing to read the TIFF and mozjpeg to encode the JPEG — the output is 10–40% smaller than TIFF-to-JPEG conversion via standard Photoshop export.

PNG to WebP: The Web Performance Upgrade

WebP was designed to replace both JPEG (photos) and PNG (graphics with transparency) with a single more efficient format. For web use, converting PNG to WebP delivers:

  • 25–35% smaller files than PNG at equivalent quality
  • Full alpha channel support — transparent PNGs convert to WebP with transparency intact
  • 97%+ browser support — Chrome, Firefox, Edge, Safari 14+, all major mobile browsers

The conversion is one-directional in terms of information: WebP lossy at quality 92 removes data that lossless PNG doesn't discard. If you need the original lossless data (for re-editing, for print), keep the PNG source and convert to WebP for web delivery only.

When PNG to WebP makes sense:

  • Website assets: logos, icons, marketing graphics, product images
  • CDN-served content where you control the format
  • Any image that currently lives on a web server as a PNG

When to keep PNG:

  • Email campaigns (major email clients including Outlook don't support WebP)
  • Files sent to external parties who may be using tools that don't accept WebP
  • Print workflows (TIFF is preferred; PNG is accepted but less standard)
  • Source files you'll need to re-edit (keep lossless PNG, convert to WebP for each delivery)

Lossless WebP vs lossy WebP: Playyy's convert to WebP tool uses quality 92 lossy WebP by default. For logos and graphics where any quality loss is unacceptable, you can also use lossless WebP — the files are larger than lossy WebP but smaller than equivalent PNG.

HEIC to JPG: Getting iPhone Photos Into Every Workflow

iPhone and iPad cameras shoot in HEIC by default — a container format based on HEIF (High Efficiency Image Format) that achieves significantly better compression than JPEG. An iPhone HEIC file is typically 40–50% smaller than equivalent JPEG at the same visual quality.

The problem: HEIC is not accepted by most web platforms, design tools, email clients, or professional applications outside the Apple ecosystem. Shopify, Adobe products (on Windows), Google Photos (on non-Apple devices), and most stock photography platforms all require JPEG or PNG.

Converting HEIC to JPEG:

  1. Upload your HEIC files to Playyy's image converter
  2. Select JPEG as the output format
  3. Download the JPEG files

The conversion reads the HEIC container and re-encodes the image data as JPEG. At quality 92 with mozjpeg, the output JPEG is visually indistinguishable from the HEIC source while being compatible with every platform.

Alternatively, you can change your iPhone settings to shoot in JPEG directly: Settings → Camera → Formats → Most Compatible. This adds about 40–50% to each photo's file size compared to HEIC, but eliminates the conversion step for everything that leaves your phone.

When to keep HEIC: If you're storing photos only on Apple devices and services (Photos library, iCloud), HEIC is the better choice — smaller files with identical quality. Convert to JPEG only when a specific destination requires it.

JPEG to PNG: When and Why

Converting JPEG to PNG doesn't recover data that JPEG compression already removed — the lossy step happened when the JPEG was created. The PNG output will be a lossless snapshot of the JPEG's current pixel data.

When JPEG to PNG conversion makes sense:

  • You need transparency: add a transparent background to an existing product JPEG. After conversion to PNG, you can remove the background and place it on any color without compression artefacts appearing at the edges.
  • You're running multiple edits on the same image: saving intermediate steps as PNG prevents additional JPEG re-encoding loss from accumulating across edit rounds.
  • A platform or tool specifically requires PNG format.

When it doesn't make sense:

  • Simply to reduce file size — PNG files are consistently larger than JPEG for photographic content.
  • To "improve quality" — JPEG artefacts don't disappear in the PNG output; they're preserved losslessly.

SVG to PNG: Making Vector Content Work Everywhere

SVG files don't render in most email clients, ad platforms, or legacy content management systems. Converting SVG to PNG is the standard approach for making vector assets work in contexts that only accept raster formats.

What happens in SVG to PNG conversion: The SVG markup is rasterized — the vector paths, fills, and text are drawn as pixels at the SVG's defined dimensions. The result is a PNG at whatever pixel dimensions the SVG specifies (or at a specific resolution you request).

Things to check before converting:

  • The SVG's defined dimensions (check the width and height attributes or viewBox). If the SVG is defined at 100×100px, the PNG output will be 100×100px — too small for most uses.
  • Font rendering: SVGs that reference external fonts may render differently depending on the conversion environment. SVGs with embedded paths for text are safer.
  • Transparency: If the SVG has a transparent background, the PNG output will preserve it.

Playyy's SVG compressor strips editor metadata before you convert — combining SVGO optimization with PNG output gives you the cleanest possible raster from your vector source.

When Converting Changes What You Can Do With the File

Every conversion to a lossy format (JPEG, WebP lossy, AVIF) is a one-way step. The data removed during encoding doesn't come back in a later conversion. A JPEG converted to PNG is a lossless container for a lossy image — not a lossless image.

This matters for workflow planning. The general rule: keep the highest-quality source (TIFF or lossless PNG) and convert for each delivery destination. Don't convert once and use the converted file as the source for the next conversion.

For teams working with product images: keep the camera original or retouched TIFF, and generate delivery formats (JPEG for Amazon, WebP for website, PNG with transparency for design use) from the same source each time. This costs slightly more storage but eliminates accumulated quality loss across the product lifecycle.

Frequently asked questions

Upload your TIFF file to an online image converter and select JPEG as the output. Playyy's image converter handles TIFF input natively via Sharp's libtiff processing — you get a JPEG at quality 92 with mozjpeg encoding. The conversion strips the TIFF container and re-encodes the pixel data as JPEG. For batch conversion of multiple TIFF files, upload up to 20 at once.
