Best Free Squoosh Alternatives in 2025
Bulk compress, convert, and edit images in your browser — more formats, more tools, same privacy-first approach as Squoosh.
Squoosh (built by Google Chrome Labs) is an excellent browser-based image compression tool — but it's designed for compressing one image at a time with side-by-side codec comparison. If you need bulk processing, format conversion, PDF tools, or a broader set of image editing features while keeping the same privacy-first, no-upload approach, PicsSizer covers all of that.

Why Switch from Squoosh to PicsSizer?
Batch / bulk processing
Squoosh compresses one image at a time — you must reload and re-upload for every file. PicsSizer's Bulk Image Compressor handles up to 100 images simultaneously with a single quality setting, downloading all results as one ZIP file.
Same privacy model, more features
Like Squoosh, PicsSizer processes images entirely in your browser with no server uploads. But PicsSizer extends this to a full toolkit: resizing, cropping, PDF tools, AI background removal, and more — all with the same local-processing privacy.
Actively maintained
Squoosh has not received significant updates since 2023 and may eventually be discontinued. PicsSizer is actively developed with regular feature releases and format support updates.
Target file size mode
Squoosh compresses by quality level — you specify a quality (0–100) and see the resulting size. PicsSizer's target-size mode works in reverse: you specify the desired file size (e.g., 100KB) and the tool automatically finds the right quality level.
PDF and document tools
PicsSizer includes Image to PDF, Merge PDF, Split PDF, and Rotate PDF — all browser-based. Squoosh has no PDF features.
More editing tools
PicsSizer adds rotate, flip, crop, watermark, blur, pixelate, redact, favicon generator, and app icon generator tools that Squoosh doesn't have. If you need an image toolkit rather than just a compressor, PicsSizer covers far more ground.
Move your Squoosh workflow to PicsSizer
Most Squoosh use cases port to PicsSizer with one extra capability — batch.
- 1
Identify your batch
Squoosh works one image at a time, so users typically stack tabs or repeat the workflow. Collect all images into one folder before opening PicsSizer.
- 2
Open Bulk Image Compressor
Visit picssizer.com/bulk-image-compressor. Drag every file in at once — up to 100 at a time. The interface looks similar to Squoosh but with a multi-file panel.
- 3
Pick format and quality
Choose the output format (JPG, WebP, AVIF) and a single quality value. The same setting applies to every file in the batch. For per-image fine-tuning, use the single-image Image Compressor with the same controls.
- 4
Export all as ZIP
Click Download — every compressed file arrives as a single ZIP with preserved filenames. Replace your Squoosh-compressed outputs in place. For deeper codec research, keep Squoosh open for the comparison view.
When PicsSizer beats Squoosh — and when it doesn't
Squoosh remains the gold standard for single-image codec research. Google Chrome Labs built it to expose every meaningful parameter of MozJPEG, OxiPNG, WebP, AVIF, and JXL encoders, with a real-time before/after view. If you're optimizing a hero image for a high-traffic page and want to nail down the exact quality-vs-bytes tradeoff, Squoosh's UI is purpose-built for that workflow.
PicsSizer targets the workflow Squoosh skipped: batch processing. Squoosh deliberately stayed single-image to keep the codec UI focused — every Squoosh user knows the frustration of reloading the tab to compress the next image. PicsSizer handles 100 images at once, applies the same quality setting across the batch, and zips the results. For internal media libraries, e-commerce product galleries, blog asset prep, or client deliverables, batch-mode is the difference between 5 minutes and 5 hours.
Both tools share the same privacy model — local browser processing, no uploads, no telemetry. PicsSizer extends the toolkit beyond compression: resize, crop, watermark, redact, background removal, PDF compression, favicon generation. Squoosh is one focused tool. PicsSizer is a workshop. Pick the one that matches your work mode.

Frequently Asked Questions
Is PicsSizer better than Squoosh?
For different use cases. Squoosh has more advanced codec controls (MozJPEG, OxiPNG, AVIF options) and an excellent side-by-side comparison mode — ideal for technical image optimization research. PicsSizer is better for batch processing, a broader tool ecosystem (PDF, watermark, resize, background removal), and users who need more than single-image compression.
Does PicsSizer upload images to a server like some alternatives?
No. PicsSizer is fully browser-based — no image data leaves your device. This matches Squoosh's privacy model, which also processes images locally.
Can PicsSizer compress multiple images at once like Squoosh can't?
Yes. Squoosh compresses one image at a time. PicsSizer's Bulk Image Compressor processes up to 100 images simultaneously and downloads them all as a single ZIP file.
Is Squoosh still maintained?
As of 2025, Squoosh hasn't received significant updates since 2023. It still works, but active development appears to have stopped. PicsSizer is actively maintained with regular updates.
Does PicsSizer support AVIF like Squoosh?
Yes. PicsSizer converts to and from AVIF format. Compression quality control for AVIF is available via the Image Converter. Squoosh's AVIF codec options (e.g., cq-level, subsample) are more granular for technical optimization work.
Can I still do A/B codec comparison without Squoosh?
Partly. PicsSizer's Image Compression Benchmark tool shows file size and visual quality across formats (JPG, WebP, AVIF) for a single image. It doesn't expose every codec parameter (MozJPEG iterations, OxiPNG levels) but covers the comparison most users need before picking a format.
Is PicsSizer open source like Squoosh?
Squoosh is open source under Apache 2.0 from Google Chrome Labs. PicsSizer is proprietary closed-source but free to use with no account, no upload, and no telemetry. The codecs PicsSizer uses (WebP, AVIF, JPEG XL via WebAssembly) are themselves open source.
When should I still use Squoosh instead?
Use Squoosh when you need (1) granular codec parameter access for image-optimization research, (2) side-by-side visual comparison of two settings on the same image, or (3) open-source provenance for compliance reasons. Use PicsSizer for everything else — batch work, format diversity, supporting tools, and modern feature development.
