Best Image Converter Chrome Extensions in 2026 — 5 Tools Compared

Chrome saves images as WebP. Websites serve AVIF. Email clients want JPG. Design tools need PNG. The modern web is a format warzone, and you need a tool that lets you convert images without friction.

We tested every major image converter tool available for Chrome in 2026 — browser extensions, web apps, and standalone tools. Here's our ranking of the 5 best options, with honest pros and cons for each.

What We Tested

We evaluated each tool on these criteria:

• Format support — which output formats are available (PNG, JPG, WebP, AVIF)?
• Privacy — does the tool process images locally or upload them to a server?
• Speed — how fast is the conversion workflow?
• Features — clipboard copy, quality control, batch processing, cross-origin support?
• Pricing — free tier limitations, premium costs?
• User experience — how many clicks to convert? How intuitive is it?

1. VKT ImageConv — Best Overall

VKT ImageConv is a free Chrome extension that does one thing exceptionally well: convert any web image to your preferred format in two clicks.

Key Features

• 4 formats: PNG, JPG, WebP, and AVIF — the only extension on this list with full AVIF support;
• Right-click conversion: Right-click any image → ImageConv → Save as [format]. Instant download;
• Copy to clipboard: "Copy as PNG/JPG/WebP/AVIF" puts the converted image on your clipboard — paste into emails, docs, chats;
• Quality adjustment: Slider control for JPG, WebP, and AVIF compression (1–100);
• 100% local: All processing happens in your browser via the Canvas API. Zero uploads, zero tracking, zero data collection;
• Cross-origin support: Service Worker architecture handles images from any CDN, even with strict CORS headers;
• Smart link cleaning: Strips tracking parameters from CDN image URLs;
• JPG white fill: Transparent PNGs get a clean white background when saved as JPG;
• 6 languages: English, Chinese, Japanese, German, Spanish, French;
• Manifest V3: Lightweight, fast, no dependencies, future-proof.

Pricing

Free tier includes all web image features — right-click save, clipboard copy, quality sliders, all four formats. Premium ($2.99/mo or $9.99 lifetime) adds drag-and-drop local file conversion and batch processing.

Pros

• Only extension with AVIF support;
• Clipboard copy is a killer feature for productivity;
• Quality sliders give you real control;
• Works on cross-origin images that break other extensions;
• No account, no tracking, no data collection;
• Available on both Chrome and Edge.

Cons

• Batch and local file conversion require premium;
• No Firefox support (Chrome and Edge only).

2. Save Image as Type — The Classic

One of the oldest "Save Image as Type" extensions for Chrome. It adds "Save as PNG," "Save as JPG," and "Save as WebP" to the right-click menu.

Key Features

• 3 formats: PNG, JPG, WebP;
• Right-click menu integration;
• Simple, minimal interface;
• Free.

Pros

• Dead simple — install and use immediately;
• Lightweight and fast;
• Well-known, large user base;
• Free with no premium tier.

Cons

• No AVIF support — the biggest gap in 2026;
• No clipboard copy;
• No quality adjustment;
• Limited cross-origin support — may fail on CDN-hosted images;
• Manifest V3 migration status is unclear;
• Infrequent updates.

Best For

Users who only need basic PNG/JPG/WebP conversion and want the simplest possible tool. If AVIF and clipboard copy don't matter to you, this is a fine choice.

3. Webp2jpg — Focused Converter

Webp2jpg is a specialized tool focused on WebP-to-JPG conversion, with some additional format support. It's available as both a Chrome extension and a web app.

Key Features

• WebP to JPG/PNG conversion;
• Batch conversion support;
• Web app version available;
• Free.

Pros

• Good at its core task (WebP conversion);
• Batch processing is useful for multiple images;
• Web app works in any browser;
• Free.

Cons

• Narrow focus — primarily WebP conversion;
• No AVIF support;
• No clipboard copy;
• No quality control sliders;
• Web app version requires uploading images to a server;
• Less active development in 2026.

Best For

Users who specifically need WebP-to-JPG batch conversion and don't need AVIF or clipboard features.

4. Squoosh — Google's Image Compression Tool

Squoosh (squoosh.app) is a web-based image compression tool built by Google. It's not a Chrome extension — it's a progressive web app — but it's widely used for image format conversion.

Key Features

• Supports many formats: JPG, PNG, WebP, AVIF, MozJPEG, OptiPNG, and more;
• Side-by-side quality comparison;
• Advanced compression settings;
• Works in any modern browser;
• Free and open-source.

Pros

• Most format options of any tool on this list;
• Side-by-side comparison is excellent for quality tuning;
• Open-source and transparent;
• Google-backed, well-maintained;
• Free with no restrictions.

Cons

• Not a right-click tool — you must open squoosh.app, drag or select a file, configure settings, and download. Much more friction than a browser extension;
• No clipboard copy;
• Single image workflow — no batch processing in the web app;
• Designed for compression optimization, not quick conversion;
• Overkill for simple "convert this image" tasks.

Best For

Developers and designers who need fine-grained compression control and want to compare quality across formats. Not ideal for quick, everyday conversions.

5. Online Converters (CloudConvert, Convertio, etc.)

Online converters are web services where you upload an image, choose an output format, and download the converted file. Popular options include CloudConvert, Convertio, Zamzar, and FreeConvert.

Key Features

• Wide format support (often 100+ formats);
• Batch conversion;
• Cloud-based processing;
• API access for developers.

Pros

• Works in any browser, no installation needed;
• Handles exotic formats (TIFF, BMP, HEIC, etc.);
• Batch processing available;
• API for automation.

Cons

• Privacy risk — every image is uploaded to a third-party server;
• Speed — 5–30 seconds per conversion depending on server load;
• File size limits — free tiers cap at 5–100 MB;
• Daily limits — typically 10–25 free conversions per day;
• Watermarks — some services add them to free-tier output;
• Account required — most services want your email;
• No clipboard copy;
• No right-click integration — you must switch tabs, upload, wait, download.

Best For

One-off conversions of exotic formats, or situations where you need batch processing and don't mind uploading. Not recommended for regular use or sensitive images.

Full Comparison Table

The Verdict: Which Should You Choose?

• Daily use, any format, maximum privacy: VKT ImageConv. The clipboard copy and AVIF support alone make it the most productive tool available;
• Simplest possible tool, PNG/JPG/WebP only: Save Image as Type. No frills, just works;
• Batch WebP conversion: Webp2jpg. Good for processing multiple WebP files at once;
• Fine-grained compression control: Squoosh. Best for developers optimizing images for production;
• Exotic format conversion (TIFF, HEIC, BMP): Online converters. Accept the privacy trade-off for format variety.

For most users, VKT ImageConv offers the best combination of features, privacy, and ease of use. It's the only tool that supports AVIF, clipboard copy, quality sliders, and cross-origin images — all while processing everything locally with zero tracking.

What to Look for in an Image Converter Extension

Before you install any image converter extension, check these things:

• Permissions: Does it need access to all websites, or just the images you click? Minimal permissions = safer;
• Privacy policy: Does it collect data? Send images to external servers? Look for "100% local processing" claims and verify them;
• Manifest version: Chrome is phasing out Manifest V2 extensions. Choose V3-native tools for long-term compatibility;
• Update frequency: Extensions that haven't been updated in a year may break with Chrome updates;
• Reviews: Check recent reviews, not just the star rating. Look for complaints about ads, data collection, or broken features;
• Format support: In 2026, any image converter worth installing should support at least PNG, JPG, and WebP. AVIF support is a strong differentiator.
