How it works

Done In 4 Simple Steps.

1

Select the batch

Add supported images and check the plan allowance and combined size.

2

Choose compression quality

Set the quality level for the batch. Start conservatively when text or fine detail matters.

3

Process and compare

Sign in, run compression and inspect each output size and any individual errors.

4

Save the useful results

Download a single image or collect completed results into a ZIP.

Image Converter

Convert one supported image to JPEG, PNG, WebP, GIF or AVIF with an explicit output-format choice.

WEBP Converter

Convert a supported raster image to WebP with adjustable encoding quality.

Background Remover

Remove a still image’s background locally and download a transparent PNG.

Image Upscaler

Image Enhancer

Apply a fixed brightness, saturation and sharpening adjustment to a supported image.

01

Introduction

Photographs and exported graphics can exceed an upload budget even when their dimensions are appropriate. Image Compressor lets you compare actual output sizes across a batch before deciding which versions to keep. Savings depend on the source format and how efficiently the original was encoded.

02

What This Tool Does

SavDown re-encodes each image on the server. JPG, PNG, WebP, GIF and AVIF keep their corresponding output format; HEIC and HEIF are delivered as JPG. PNG encoding does not use the quality slider in the same way as lossy JPEG encoding.

Key features

Image Compressor Features

Choose quality from 10–100, manage the upload list, inspect successes and failures, and download individual results or a ZIP.

Batch Processing

Run the selected images together while retaining separate results and failure messages.

Quality Control

Adjust the quality level for supported lossy encoders instead of accepting a single fixed preset.

Measured Sizes

Read source and result byte sizes rather than relying on a promised saving.

ZIP Delivery

Collect completed files for a site update or handoff without downloading each one separately.

HEIC Handling

Receive a JPG when a supported HEIC or HEIF image is compressed.

Per-File Recovery

Review failed entries while keeping the successful outputs available.

Benefits

Why People Actually Use It.

Beyond the headline features, here is what the tool unlocks in real workflows.

Meet Upload Budgets

Compare the actual result with the size limit of the form or service you plan to use.

Simplify Asset Handoff

Bundle the usable files for a teammate with a single ZIP download.

Protect Important Detail

Choose a less aggressive setting for lettering and diagrams rather than treating every image like a photograph.

Best practices

Use It The Right Way.

A few habits that consistently produce the best results.

1Keep the original images and compare fine detail at full size before replacing them.
2Resize oversized dimensions separately when compression alone is insufficient.
3Check PNG results independently because the lossy-quality control does not apply equally to every format.
4Stay within both the combined size allowance and the file-count hint.

Supported inputs

Supported Inputs and Compatibility

Up to 25 MB per file and 50 megapixels decoded. A filename extension alone does not guarantee that an image can be decoded. Use a browser that supports file selection and downloads. Combined uploads are capped at 100 MB and the file count follows your plan. Compression can produce a larger file; a reduction percentage is not guaranteed.

Tips & tricks

Power-User Tips.

Small habits that save time and produce better files.

Try a moderate quality setting first, then lower it only if the output is still too large.

Avoid recompressing the previous compressed download; use the original for each attempt.

Download successful results before refreshing the page.

Use Image Resizer when excessive pixel dimensions are the main cause of file size.

Why choose SavDown

Why This Tool?

SavDown puts batch outcomes beside the size comparison, making it easier to distinguish a useful reduction from an unsuccessful file. The individual downloads and ZIP option suit an asset handoff, while keeping failures visible gives you a concrete next step for sources that need attention.
